复杂地质条件下基于折线滑动面法高边坡支护设计——以广东省肇庆市某边坡为例

Design of High Slope Support Based on Folding Sliding Surface Method under Complex Geological Conditions-Taking a slope in Zhaoqing City,Guangdong Province as an example

针对广东肇庆市某复杂地质条件下高边坡,采用Geo5软件采用折线滑裂面,运用摩根斯坦—普赖斯法和不平衡推力法计算潜在的滑裂面,并运用“锚索格构+支护桩+土钉墙+扶壁式挡墙+放坡”等几种支护形式的组合支护,进行计算得到支护的安全系数值均达到边坡设计的规范要求。

In this paper,the folding line sliding surface is used by Geo5 software for the high slope under a complex geological condition in Zhaoqing,Guangdong Province.The Morgan Stanley-Pryce method and the imbalance thrust force method are used to calculate the potential slide plane.The combination support of several support forms,such as anchor cable lattice,support pile,soil nail wall,buttress retaining wall and grading are adopted.The safety factor values of the support are calculated to meet the specification requirements of the slope design.
