3D Finite Element Analysis of Deep Excavation in Central Jakarta using Total and Effective Shear Strength Properties
Abstrak (Abstracts)

This paper presents a study on 3D finite element analysis of a large-scale deep excavation in Central Jakarta. The soil, Central Jakarta clay, is modeled by both Hardening Soil and Mohr-Coulomb model in Plaxis 3D. The total and effective stress analyses under undrained conditions were used to model the short-term undrained conditions of the clay during excavation. The input soil properties were established using data based on an extensive site investigation program including in situ and laboratory tests, and empirical relationships with standard penetration numbers (SPT-N). The top-down construction method and a supporting system of concrete slabs are also considered in the numerical model. The numerical results are compared with measured wall deformation from inclinometers at a certain distance from the corner of excavation. The simulations using drained and undrained soil shear strength (Undrained A and B functions in Plaxis 3D) are also compared and discussed.
