软弱结构面岩质边坡支护工程实例与分析

Example and analysis of supporting project for weak structural plane rock slope

以软弱结构面岩质边坡支护工程为研究对象,结合结构面赤平投影分析了该边坡可能破坏的形成机理,分析边坡工程地质条件,破坏机理为蠕滑-拉裂式滑动或平面滑动的软弱结构面岩质边坡,采用格构梁+锚索+锚杆+挂网喷砼支护结构设计方案可行,通过实例证明边坡支护设计取得了良好的社会效益和经济效益,可为其它类似工程提供应用参考。

Taking the supporting project for weak structural plane rock slope as the research object,we analyzed the formation mechanism of possible damage of the slope using structural stereographic projection,and analyzed the geological conditions of the project. For the slope of which the damage mechanism was creep -slipping or plane sliding,the supporting scheme of lattice structure + anchor cable + anchor + hanging net with concrete pouring was feasible. It was proved in practice that the slope supporting scheme had achieved good social and economic benefits,and could provide application references for other similar projects.
