孟底沟水电站开关站边坡稳定性分析与支护设计OA
Stability Analysis and Support Design of Switch Station Slope of Mengdigou Hydropower Station
孟底沟水电站工程区区域地质构造复杂,枢纽区边坡危岩体分布广,蚀变岩发育.开关站开挖边坡主要为强卸荷Ⅳ类岩体,边坡存在多处小断层,节理裂隙及蚀变岩带随机分布,局部地形陡峻.笔者分析了开关站边坡可能存在的各种变形破坏模式,采用平面极限平衡下限解法,对边坡整体稳定性和潜在滑移块体的稳定性进行了计算,提出了边坡的支护方案,为工程设计和施工提供了重要依据.
The Engineering area of Mengdigou Hydropower Station is characterized by complex geological struc-ture,wide distribution of dangerous rock masses on the slopes of the hub area,and developed altered rock.The excavation slope of the switch station is mainly strong unloading Class Ⅳ rock mass.There are many small faults on the slope,joints,fissures and altered rock belts are randomly distributed,and the local topography is very steep.In this paper,the deformati…查看全部>>
