Description:
The construction of the cut-and-cover tunnels and depressed roadways of the Central Expressway (CTE) Phase II, Singapore, involved deep excavations. An extensive instrumentation program was carried out to monitor the behaviour of the excavations. The performance of three instrumented excavations from the construction of the CTE Phase II have been documented and analyzed using the finite element method (EXCAV) or finite difference method (FLAC). The results of the analyses show that the computed wall movements agree well with field measurements of wall movement and the computed wall bending moments generally agree quite well with those obtained from back-calculation. Key words: deep excavation, stiff clay, numerical analysis, displacements.
