The increase in demand for underground tunnels in Singapore has added many challenges to tunnelling problems beyond the capability of analytical or empirical methods. The prospect of using 3D numerical analysis in analyzing complex practical applications is becoming more common. The paper presents the application of finite element analysis to assess the soil-structure interactions in real tunneling problems. A benchmarking study was first carried out on a centrifuge test by Ong et al. (2013) using a three-dimensional finite element method for the basic understanding of soil responses to tunneling. FE studies were then extended to a practical application with the field data from a Singapore MRT project, Bendemeer Station, Downtown Line 3 (DTL-3).
