高陡边坡危岩体治理技术

杨房沟水电站自然边坡高陡,边坡岩石节理发育,浅部岩体卸荷作用明显,局部岩体松动,山脊突出或边坡陡峻的局部形成了危岩体、危石群等,严重威胁下部建筑物、人员及设备安全。笔者通过分析危岩体特点,确定了危岩体治理的总体目标、原则及设计方法,提出了治理方案、施工技术及监测、预警等综合措施,解决了边坡稳定及安全问题。

Treatment Technology of Dangerous Rock Mass at High and Steep Slope

The natural slope of Yangfanggou Hydropower Station is high and steep,rock joints are developed,the unloading effect of shallow rock mass is obvious,the local rock mass is loose,and the dangerous rock mass and rock group are formed at protruding ridges or part of steep slope,which seriously threatens the safety of structures,personnel and equipment below.Based on analysis of characteristics of dangerous rock mass,the overall treatment target,principle and design method of dangerous rock treatment are determined,and comprehensive measures such as treatment scheme,construction technology,monitoring and early warning are put forward to solve the problems of slope stability and safety.
