摘　　要：以云南滇西山区某二级公路支挡结构基础设计项目为依托,对原设计的衡重式挡土墙和优化后的锚杆扩大基础支挡结构进行了比选。结果表明:采用锚杆扩大基础支挡结构,减少了工程量,节约了投资,且形式美观、轻盈,与周围的景观较为协调,安全性也能满足规范要求。Based on the retaining structure foundation design project of a secondary highway in west mountainous areas of Yunnan Province,the original design of balance weight retaining wall and anchor bolt expanded foundation retaining structure after optimization are compared. Results show that： anchor bolt expanded foundation retaining structure can reduce the work quantity and save investment, its form is beautiful,light and properly coordinated with surrounding landscape,and security can meet requirements of specification.
