摘要： 理正岩土软件是工程上最常用的计算软件，Plaxis是专业的岩土有限元软件，现同时对某项目基坑支护设计进行计算，使用理正软件计算得出的结果为，最大沉降14 mm、最大位移18.28 mm，使用Plaxis软件对其计算时，可以得出结果为，最大地表沉降15.81 mm、最大位移20.71 mm，进行相互对比，分析出更适合的软件，为类似的基坑支护工程设计计算提供一些参考。

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.

Key words: Deep Excavation Support, Lizheng Geotechnical Software, Displacement, Plaxis Software
