Abstract: Lizheng commercial software is one of the most used analytical software in the geotechnical engineering projects. Plaxis is also a geotechnical specialty finite element software. This paper presents a case history of deep excavation supporting system design and analysis using both software. The results are the following: the maximum settlement of 14.0 mm and the maximum lateral deflection of 18.28 mm were obtained by Lizheng software, whereas, the maximum settlement of 15.81 mm and the maximum lateral deflection of 20.71 mm were obtained by Plaxis software. Using different software can improve the prediction results and help in selection the most appropriate software for the project.
