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