Rosewood Hotel Project consists of 6 basements by using a diaphragm wall as a soil protection system. Elevations of Rosewood Hotel basements are -2.9, -6.5 -9.25, -11.95, -14.65 and -18.9 m. depth from the ground surface. Final excavation depth of this project is -24.2 m. from the ground surface which is area intended for a lift pit. Due to the fact that the final depth of this project is very deep, the effect of water pressure was also considered. Finite Element Method (FEM) was carried out to predict behavior and displacement of the diaphragm wall which is used as a soil protection system. In addition, the Mohr-Coulomb soil modeling was used as failure criteria of the FEM analysis. Measured lateral movement of the diaphragm wall by means of inclinometer at all stages of construction was compared with analytical results from FEM prediction. The predicted diaphragm wall displacement by FEM agrees well with field performance.
