温宿县天山大峡谷景区崩塌发育特征及稳定性评价

摘要

Collapse is the main geological hazard in the Tianshan grand canyon scenic spot.Sliding is the main basic types in this paper.The main loads to cause collapse in the reservoir are weight of unstable rock,fissure water in nature,fissure water in strong precipitation and earthquake force.There are four types of load combination.According to both unstable rock model and load combination,provides the theoretical foundation in governing the collapse disaster.%崩塌是温宿县天山大峡谷的主要地质灾害.根据危岩体失稳破坏的模式,研究区主要发育有滑移式破坏.温宿县天山大峡谷景区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.
