摘　　要：介绍在山区地质条件复杂、岩层出露不均匀地区地基处理项目设计的工程实例,着重介绍了CFG地基处理方案的设计思路以及相关计算分析。结果表明原条形基础调整为筏板加条形基础,增加基础刚度,采用CFG桩复合地基处理,取得了良好的经济效益,为此后类似工程施工提供了良好的借鉴。By introducing the engineering example of foundation treatment project design in mountainous areas with complex geological conditions and uneven rock outcrop,the design idea and relevant calculation analysis of CFG foundation treatment scheme are mainly introduced.The results show that through adjusting the original strip foundation to raft and strip foundation,increasing the foundation stiffness,and adopting the CFG pile composite foundation treatment,good economic benefits are obtained,which provides a good reference for similar engineering construction.
