摘　　要：高大建筑物为拓展地下空间或保证本身的稳定性,在建设时会涉及深基坑工程施工,深基坑工程安全施工的关键在于支护结构稳定。文章借助Midas GTS NX三维有限元分析软件,针对基坑开挖后支护结构的变形情况进行了有限元模拟,并将深基坑工程支护结构模拟的位移情况与实际位移情况进行对比分析,检验了基坑支护设计的合理性、安全性和经济性,可为相关基坑支护设计提供依据和经验。In order to expand the underground space or ensure the stability of tall buildings,the construction of deep foundation pit engineering will be involved in the construction.The key to the safe construction of deep foundation pit engineering is the stability of support structure.With the help of Midas GTS NX threedimensional finite element analysis software,the finite element simulation is carried out for the deformation of the support structure after the excavation of the foundation pit,and the simulated displacement of the support structure of the deep foundation pit engineering is compared with the actual displacement.The rationality,safety and economy of the foundation pit support design are verified,which can provide basis and experience for the relevant foundation pit support design.
