高速铁路CFG桩复合地基沉降的数值研究

Numerical simulation research on foundation deformation of CFG pile composite on high-speed railway

借助有限元分析软件FLAC,对受竖向荷载作用下CFG复合地基进行数值模拟,分析桩间距、桩长、垫层刚度、填土高度、桩帽直径变化对路基变形影响,为CFG桩复合地基变形理论研究提供依据。

With the help of finite element software FLAC,the article focus on the deformation of CFG pile composite under vertical loads,analysis various factors affecting the deformity of CFG pile composite foundation,such as pile spacing, length,cushion stiffness,fill height,pile cap diameter,provide theoretic framework for CFG pile composite foundation.
