摘　　要：边坡安全监测主要目的是在开挖支护期及运行期的稳定性状态做出定性评价,通过量化分析结果反馈及验证设计方案的合理性,指导开挖支护施工。结合金川水电站泄洪洞进口边坡安全监测资料分析成果,分析边坡优化设计开挖及支护措施效果,可为金川水电站泄洪洞进口边坡施工提供支撑。The main purpose of the slope safety monitoring is to make a qualitative evaluation of the stability state during the excavation and support process and the operation period,and to guide the excavation and support construction by feeding back the results of quantitative analysis and verifying the rationality of the design scheme.Based on the analysis results of the safety monitoring data of the inlet slope at the spillway tunnel of Jinchuan Hydropower Station,this paper analyzes the performance of excavation and support measures in the optimal design of the slope,which provides data support for the construction of the inlet slope of the spillway tunnel of Jinchuan Hydropower Station.
