CFG桩在高速铁路地基加固处理中的有效应用

随着我国基础设施建设的加快及设计理念的转变,高速铁路在铁路设计中所占比例越来越大,路基工后沉降要求较高,如何采用地基加固措施满足工后沉降的要求成为高速铁路路基工程地基加固处理的关建。以郑徐铁路客运专线永城北站路基加固为例,详细介绍了CFG桩在高速铁路地基加固处理中的有效应用。

The Effective Application of CFG Pile in High-speed Railway Foundation Reinforcement

With the speeding up of infrastructure construction and the changing of design concept, the proportion of high-speed railway in the railway design is bigger and bigger. Due to the requirements for the subgrade＇ s post-construction settlement are higher,how to adopt foundation reinforcement measures to meet the requirements of post-construction settlement has become the key of the foundation reinforcement of high-speed railway subgrade engineering. Taking the foundation reinforcement of Yongcheng North Station of Zhengzhou-Xuzhou railway passenger dedicated line as an example, this paper introduces in detail the effective application of CFG pile in high-speed railway foundation reinforcement.
