摘　　要：通过Midas GTS NX有限元软件分析以及现场监测实例,研究狭长形深基坑的变形规律和影响其变形的主要因素和次要因素,为基坑围护设计和施工提供重要依据,使基坑监测工作有的放矢,把监测工作重心放在变形较大、危险性较大的部位。By the analysis and comparison of finite element software Midas GTS NX and the actual situation of field monitoring results,this paper studies the deformation rule of the long narrow deep foundation excavation,it finds out the main factors and the secondary factors affected the deformation,provides important basis for the design and construction of foundation excavation bracing. So the foundation excavation monitoring working would be more purposeful,the monitoring work can focus on the more dangerous area and large deformation area.
