Abstract: Pore pressure is one of the major factors influencing stability of soil surrounding an excavation. The study of pore pressure response surrounding the excavation is crucial for geotechnical designs. PLAXIS is finite element analysis tool for geotechnical engineering that has established a good reputation in the geotechnical industry. The application of PLAXIS in actual geotechnical problems has been adopted by the industry, and practiced frequently. It is convenient to use the Mohr-Coulomb model for a relatively quick and simple first analysis of the geotechnical problem considered. However, in many cases, provided one has good data on dominant soil layers, it is recommended to use the Hardening Soil model in an additional analysis. Good quality data from one type of test can be supplemented by data from correlations and in situ testing. This study considers Hardening Soil model and Modified Cam Clay model as two alternatives to Mohr-Coulomb model for application in actual case analysis. A comparison of three models will be done against in situ instrumentation data in order to find out which model is a better practice in the case study of Farrer Park Station.
