摘　　要：粉砂质泥岩顺层边坡在工程施工过程中,在开挖卸荷、持续降雨等不利条件下,容易出现基岩基础面裸露、临空问题,形成切角破坏现象,而且岩体遇水软化、失水易崩解,进而带动滑动面以下发生顺层滑移变形,致使边坡呈现极不稳定状态。因此,本文采用喷锚支护对顺层岩边坡进行加固处理,通过岩质边坡稳定性计算,确定合理锚杆支护参数,保证工程安全稳定、经济可行,以期对类似工程的加固设计提供参考价值。In the process of engineering construction,under the unfavorable conditions such as excavation unloading and continuous rainfall,the bedrock foundation surface is exposed and empty,resulting in incisal failure,and the rock mass is softened and easily disintegrated when encountering water,which then leads to the bedding sliding deformation below the sliding surface,resulting in the slope presenting an extremely unstable state.Therefore,this paper adopts shotcrete anchor support to strengthen the bedding rock slope.Through the stability calculation of rock slope,the parameters of bolt support are reasonably determined to ensure the safety,stability and economic feasibility of the project.In order to provide reference value for similar engineering reinforcement design.
