| 摘 要： | 岩土工程有限元分析软件PLAXIS2D已经被广泛应用于基坑开挖的数值模拟计算中,但关于其模拟计算基坑开挖工程的适用性问题,目前还未见有相关文献进行深入分析.鉴于此,利用PLAXIS2D对3个实际深基坑开挖工程进行了数值模拟计算,通过计算结果与实测结果的对比,分析了PLAXIS2D在基坑开挖工程中的适用性；在此基础上,对应用PLAXIS2D进行基坑开挖数值模拟计算的适用条件进行了探讨,研究结论对正确应用PLAXIS2D进行基坑开挖工程的模拟计算具有较好的参考价值.

| Abstract: | The geotechnical engineering finite element analysis software,PLAXIS2D,has been widely used for numerical simulation in foundation pit excavations.However,few literatures had made a detail analysis on applicability of the software PLAXIS2D used for foundation pit excavations at present.In view of this,three actual foundation pit excavation engineerings were simulated by PLAXIS2D.By comparison of computing results and measured ones,applicability of PLAXIS2D has been investigated.Further,the application conditions of PLAXIS2D used for foundation pit excavation engineerings have been discussed.The conclusion can provide some references for the proper use of PLAXIS2D in foundation pit excavations. |
