深基坑桩锚支护变形有限元分析

桩锚支护具有一系列优点，已成为基坑支护中最常用的方法之一。通过深圳某深基坑开挖过程的有限元数值模拟，得出了桩体水平位移、桩后土体沉降的变化规律，并将计算位移值与实际监测结果相比较，验证了有限元数值模拟的合理性，为深圳某深基坑支护提供了重要依据。

FEM Analysis on Deformation of Pile-anchor Support for Deep Foundation Pit

Pile-anchor support, with series of features, has become one of common used supporting methods for foundation pit. Through finite element numerical simulation on excavation of certain deep foundation pit in Shenzhen, the change law of pile body's horizontal displacement and soil mass's settlement behind the pile could be obtained. The comparison between calculated value of displacement and the monitored result demonstrates the rationality of finite element numerical simulation and offers important basis for supporting in the deep foundation pit in Shenzhen.
