| 摘 要： | 采用大型有限元分析软件MIDAS—GTS建立反映浅圆仓上部结构动态施工过程的上部结构一桩基一地基共同作用的三维数值分析模型，对施工过程中整体结构及地基的受力变形情况进行动态模拟，通过三维数值分析，得到施工过程中管桩及桩间土的受力情况变化及变形情况，得到其随施工过程中的变化发展规律，为类似工程的设计及施工提供参考。

| Abstract: | To investigate the interaction effect of large squat silo, MIDAS-GTS is used to build the 3D finite element model （FEM） of squat silo superstructure-pile-soil interaction. The deformation of the whole structure and foundation is simulated in the construction stage. The three-dimensional numerical analysis achieves the force and deformation of the pipe pile foundation, and their developing law in the dynamic construction process. It provides a reference for the design and construction of similar projects. |
