The joy of modelling practical deep excavations in soft clay using SIGMA/W

Deep excavation in Singapore is challenging as the local geology consists of thick layer of soft clay with occasional lenses of sand and peaty/organic soils coupled with a high ground water table.

Engineers need to predict the retaining wall lateral deflection and the adjacent ground vertical settlement, which has strict limits set by the building control authority. Detailed analysis with GeoStudio or other FEM program is essential for submission to authorities before construction. This presentation describes how GeoStudio was used to model deep excavation problems.
