以沪昆客专贵州玉屏某路基段地基处理工程为例,针对路基基底岩溶发育的工程地质问题,采用CFG桩复合地基方案进行加固处理,进行了CFG桩复合地基承载力的设计验算和处理效果检测,在对工程地质条件研究分析的基础上,较为系统地提出了各种不同的岩溶工程地质条件下CFG桩设计和施工的应对措施。
Taking the foundation treatment project of a certain section of Yuping Passenger Dedicated Section in Shanghai-Kunming Passenger Dedicated Area as an example, aiming at the engineering geological problems of subgrade karst development, CFG pile composite foundation is used to reinforce the bearing capacity of CFG pile composite foundation. Based on the research and analysis of engineering geological conditions, various measures to design and construct CFG piles under different karst engineering geological conditions are systematically proposed.
