Numerical simulation of staged braced excavation in sand ~ O6 MRT station

Hama Salih, Samal and Mirza Hassan, Mohammad and Shiau, Jim and Hossain, Zakaria (2018) Numerical simulation of staged braced excavation in sand ~ O6 MRT station. International Journal of GEOMATE, 14 (43). pp. 104-111. ISSN 2186-2982


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.
