Abstract

A numerical model for long-term drained analysis of staged excavation is developed and
validated with a case history in this paper. Kaohsiung O6 station in Taiwan is selected for this purpose. A
complete soil-structure interaction is considered in the current analysis which involves structural elements for
diaphragm wall and strutting with preloading. FISH scripts are used to simulate staged strutted excavation
using the finite difference program FLAC. Within the framework of drained analysis for excavation in the
sand, dewatering is performed for each stage of the excavation work. Field monitoring data from other
published sources are used to compare with the results produced by the numerical model. The main purpose
of this paper is to demonstrate the usefulness of the development in assisting design and monitoring
construction of deep braced excavation. The developed model can be used to assist future design and
construction projects.
