摘　　要：采用Geo-Slope软件对高速铁路CFG桩进行分析,考察不同垫层结构、桩径、桩间距、有无桩帽和桩帽大小等设计参数对地基沉降的影响,从而为试验段CFG桩复合地基设计方案提供依据,并进一步对试验段设计方案进行沉降分析,可为类似工程提供参考。Using Geo-Slope software to analyze the CFG piles of high-speed railway, thus find out the impact of such design parameters as bedding structure, pile diameter, piles spacing, having pile cap or not, size of pile cap, etc. on foundation settlement. The research fruits can provide the basis for project design of CFG pile compound foundation at test section. Furthermore, the settlement of test section with such design project is analyzed, which can be consulted by similar engineering.
