黄河炳灵水电站枢纽区危岩体发育特征及稳定性研究

Study on the Development Characteristics and Stability of Dangerous Rock Mass in the Hub Area of Bingling Hydropower Station on the Yellow River

黄河炳灵水电站枢纽位于峡谷区,地形高陡,危岩体稳定问题较为突出,危岩体的崩滑曾对电站正常运行产生较严重的影响。为消除危岩体危害影响,在详细勘察的基础上,通过定性和定量评价方法 ,对枢纽区危岩体发育特征、形成机制、稳定性等进行系统地分析评价。进一步,设计和实施针对性的防治处理措施,保证电站长期运营安全。研究成果可为西部山区水电工程危岩体防治工作提供借鉴。

The Yellow River Bingling hydropower station is located in the canyon area.The terrain is high and steep,and the stability problem of dangerous rock mass is more prominent.The collapse of dangerous rock mass has had a serious impact on the normal operation of the power station.In order to eliminate the influence of dangerous rock mass,on the basis of detailed investigation,the development characteristics,formation mechanism and stability of dangerous rock mass in the hub area are systematically analyzed and evaluated by qualitative and quantitative evaluation methods.Further,design and implement targeted prevention and treatment measures to ensure the long-term operation safety of the power station.The research results can provide reference for the prevention and control of dangerous rock mass in hydropower projects in western mountainous areas.
