崩塌是库尔勒市铁门关水电厂的主要地质灾害。根据危岩体失稳破坏的模式,研究区主要发育为滑移式破坏。库尔勒市铁门关水电厂内岩质崩塌破坏的主要荷载有危岩体自重、天然状态的裂隙水压力、暴雨状态的裂隙水压力和地震力,可以构成4种荷载组合。据此,运用极限平衡理论及岩体结构理论建立了岩质崩塌破坏的计算模型,并对滑移式破坏模式的稳定性进行了计算,为岩质崩塌灾害的治理提供了理论依据。
Collapse is the main geologic hazard of Tiemenguan hydropower plant in Korla. According to the failure mode of dangerous rock mass, the main development of the study area is the sliding failure. The main load of rock mass collapse and destruction in Tiemenguan hydropower plant in Korla is that there are four kinds of load combinations, which are dead weight of rock mass, crevice water pressure of natural state, crevice water pressure of stratospheric state and seismic force. Based on this, the calculation model of rock mass collapse and failure is established by the theory of limit equilibrium and the theory of rock mass structure. The stability of the failure mode is calculated, which provides a theoretical basis for the management of rock mass collapse.
