Tras la aprobación del diseño, se obtuvo un modelo preliminar completo BIM del túnel. Debido a las distintas tecnologías existentes detrás del modelado de información de construcción (Building Information Models, BIM) y el modelo de Leapfrog, los modelos no podrían integrarse en un entorno común sin perder información. Sin embargo, la geometría del túnel transformado en Leapfrog Works permitió la extracción de varios modelos diferentes combinados para predecir con precisión los volúmenes de excavación, la distribución y cantidades de cada tipo de suelo y la identificación de discontinuidades estructurales entrecruzadas críticas. La visualización ayudó en la definición del programa de investigación y mucho más. La información y los gráficos extraídos del modelo de Leapfrog Works se utilizaron para definir la distribución de soporte a lo largo del túnel. Esto se utilizó como base para generar la malla discretizada para los cálculos de los elementos finitos.

Resultados

El uso de Leapfrog Works para el proyecto de tunelización permitió la inmediata visualización de las condiciones del suelo sobre la base de los unívocos datos de entrada. Estos datos se podrían utilizar para cálculos posteriores y análisis potencial de estabilidad y deformación. Beneficios de uso del software incluido:

  • Rápido y fácil de combinar distintos tipos de datos. Leapfrog Works les permitió a los modeladores utilizar distintos y complejos tipos de datos recogidos de estudios teóricos y de la investigación in situ.
  • Visualización y comprensión rápidas. La evaluación de la viabilidad, la identificación de conflictos entre los diferentes modelos, la comprobación de las especificaciones, la programación y el cálculo de costos de manera simultánea en diferentes puntos de vista ofrece mucho más control sobre el diseño que comprobar los dibujos en PDF, las hojas de programación, las especificaciones y las estimaciones cuantitativas. Estas ventajas serán mayores durante la construcción, cuando los cambios se pueden evaluar casi en tiempo real y registrar fácilmente junto con la información de aprobación.
  • El acceso a un modelo geológico de última tecnología. Leapfrog Works es una herramienta avanzada y especializada de modelado geológico, diseñada específicamente para modelar fallas, intrusiones y depósitos.
  • Simplificación del proceso de refinamiento. Los modeladores pueden incorporar nueva información con facilidad. La complejidad de la estructura geológica se controló durante la excavación del túnel existente, a medida que las condiciones geológicas cambiaban en distancias cortas. Se incorporaron al modelo el registro diario de frentes geológicos y el monitoreo geotécnico y topográfico. Este proceso puede continuar durante la construcción del segundo túnel.

Response

Defining the geological structure along the tunnel tube
The 3D model was built based on the extensive geological data from previous investigation and construction phases, upgraded with new findings. The single model used all available loggings, map faces, and measurements.

Says Tina Zivec, “The extensive interdisciplinary experience of Seequent’s development and support team enabled them to quickly understand the problem we faced with building the model in the most challenging disciplines.”

Due to a lack of borehole data the model was built by determining the fault system. Major faults were determined as GIS polylines and aligned to the topography. Modelled faults and structural data from outcrops were then corrected to geological cross-sections along the tunnel alignment.
Structural data from detailed geological profiles, based on geological face logging during the excavation phase, were used for orienting fault planes in the tunnel level.

The generated fault system cut the 3D model into numerous fault blocks. Appropriate lithostratigraphic units were assigned to each block. From the resulting 3D model, lithological and structural properties were extracted to create detailed geological profiles, as well as a structural model for extrapolating structural properties to the planned tunnel tube as a DFN (Discrete Fracture Network).

The 3D model allowed users to predict the location and orientation of major fault systems, general ground conditions and rock mass behaviour and aided designing support types for constructing the new tunnel tube.

Information Management

In addition to aiding significantly in the design of the new tunnel tube, Leapfrog Works also enabled synergy with BIM processes. A Leapfrog Works model is essentially an information model built under different standards.

Leapfrog Works represents a fast, powerful and user friendly software, with good graphics, fast calculations and interdisciplinary ability for including different structures.

Tina Zivec, Geologist, Elea


Following the design approval, a full preliminary tunnel BIM model was produced. Due to different technology behind BIM and the Leapfrog model, models could not be integrated in a common environment without losing some information. Nevertheless, transformed tunnel geometry in Leapfrog Works allowed the extraction of several different combined models to precisely predict excavation volumes, distribution and quantities of each ground type and the identification of critical intersecting structural discontinuities. Visualisation helped in defining the investigation program and much more. Information and graphics extracted from the Leapfrog Works model were used to define the support distribution along the tunnel. This was used as a basis to generate discretized mesh for Finite-Element calculations.

Outcome

Using Leapfrog Works for the tunnelling project allowed the ready visualisation of ground conditions based on unambiguous input data. This data could be used for further calculations, stability and deformation potential analysis. Benefits of using the software included:

  • Fast and easy combining of different data types – Leapfrog Works allowed the modellers to use complex and varied types of data collected from both desk study and in situ investigation.
  • Rapid visualisation and understanding – Evaluating feasibility, identifying clashes between different models, checking specifications, scheduling and costings simultaneously in different views gives far more control over design than checking PDF drawings, time schedule sheets, specifications and bills of quantities. These advantages will be enhanced during construction when changes can be evaluated in almost real time and easily recorded along with approval information.
  • Access to state of the art geological modelling – Leapfrog Works is an advanced, specialised geological modelling tool specifically designed to model faults, intrusions and deposits.
  • Facilitating a process of refinement – Modellers are able to readily incorporate new information. The complexity of the geological structure was monitored during the excavation of the existing tunnel tube, as the geological conditions changed in short distances. Daily geological face logging, geotechnical and surveying monitoring was incorporated into the model. This process can continue during construction of the second tunnel tube.

El proyecto del túnel Karavanke, ELEA IC (Eslovenia)

El proyecto

El túnel Karavanke, construido en los años 80, corta los Alpes entre Eslovenia y Austria y representa un punto crítico en el Corredor X del Transporte Paneuropeo. La necesidad de mejorar la fluidez del tráfico y la seguridad vial llevó, en el 2013, a la planificación de un segundo túnel.

El diseño del segundo túnel está representado por un túnel de 7820 m de dos carriles con hasta 1000 m de sobrecarga. La geología es muy compleja debido a la imbricada estructura de ventilador, que se ha formado como una matriz de superposición de pliegues por propagación de las fallas. El túnel inicial se encontró con condiciones geológicas difíciles con frecuentes y fuertes entradas de agua, sobreexcavaciones y detección de metano. Una serie de investigaciones geológicas, geotécnicas e hidrogeológicas realizadas desde la década del 70 dio lugar a una extensa documentación del proyecto.

La empresa de consultoría interdisciplinaria Elea iC, el socio principal de la Empresa Conjunta Karavanke, utiliza Leapfrog Works para modelar la geología como parte del proyecto Idea Phase de la parte eslovena del segundo túnel.

Situación

Tradicionalmente, el modelado geológico en 3D en la industria civil se limitaba a la interpretación en 2D de un entorno en 3D. Este proceso era lento, con pérdida de información entre las secciones e interpretaciones subjetivas de las condiciones geológicas y evaluación del riesgo potencial. Las interpretaciones en 2D manuales también son difíciles a la hora de actualizar el aumento de riesgo. El proyecto del túnel Karavanke y el amplio conjunto de datos le presentaron a Elea IC la oportunidad de probar las tecnologías emergentes y mover la ingeniería geológica, geotécnica y tunelización a otro nivel.

Definición de la estructura geológica a lo largo del túnel
El modelo en 3D se construyó sobre la base de los numerosos datos geológicos de las fases previas de investigación y construcción, actualizados con nuevos hallazgos. El modelo único utilizó todos los registros de datos, los frentes de los mapas y las mediciones disponibles.

Tina Zivec dice “La amplia experiencia interdisciplinaria del equipo de desarrollo y el apoyo de Seequent les permitió comprender rápidamente el problema que enfrentamos con la construcción del modelo en las disciplinas más desafiantes”.

Debido a la falta de datos de perforaciones, el modelo se construyó mediante la determinación del sistema de fallas. Las fallas principales se determinaron como polilíneas SIG y se alinearon a la topografía. Las fallas modeladas y los datos estructurales de afloramientos fueron corregidos a las secciones transversales geológicas a lo largo del trazado del túnel.
Los datos estructurales de los perfiles geológicos detallados, basados en el registro de los frentes geológicos durante la fase de excavación, se utilizaron para orientar los planos de las fallas a nivel del túnel.

El sistema de fallas generado cortó el modelo en 3D en numerosos bloques de fallas. A cada bloque se le asignaron las unidades litoestratigráficas adecuadas. A partir del modelo en 3D resultante, se extrajeron las propiedades litológicas y estructurales para crear perfiles geológicos detallados, así como un modelo estructural para la extrapolación de las propiedades estructurales del túnel planeado como una red de fractura discreta (Discrete Fracture Network, DFN).

El modelo en 3D les permitió a los usuarios predecir la localización y orientación de los principales sistemas de fallas, las condiciones generales del suelo y el comportamiento de las masas rocosas, así como los tipos de apoyo de diseño asistidos para la construcción del nuevo túnel.

Gestión de la información

Además de ayudar de manera significativa en el diseño del nuevo túnel, Leapfrog Works también permitió la sinergia con los procesos de modelado de información de construcción (Building Information Models, BIM). Un modelo de Leapfrog Works es básicamente un modelo de información construido conforme a diferentes estándares.

Leapfrog Works representa un software rápido, potente y fácil de usar, con buenos gráficos, cálculos rápidos y la capacidad interdisciplinaria para incluir estructuras diferentes.
