摘　　要：水库滑坡具有致灾机理复杂,风险防控难度大的特点。历年来水库滑坡灾害造成了多起人员伤亡和巨大经济损失。系统地梳理了水库滑坡的研究现状,学者普遍认为水库水位“上升—下降”周期性变化是诱发水库滑坡的主要原因,岩土体软化、浮托力和动水压力是灾变的作用方式。如何揭示降雨和水库水位变化耦合作用下滑坡变形破坏机制、如何描述滑坡和涌浪的复杂行为、如何开展水库滑坡早期治理是水库滑坡研究面临的关键问题,也是重点与难点。提出水库滑坡复杂灾变机制与稳定性评价、滑坡涌浪灾害链模拟与预测、消落区岩体裂化早期防控研究三方面亟待深入的研究方向。Reservoir landslide has the characteristics of complicated disaster mechanism and difficult risk prevention and control.Over the years,reservoir landslide disasters have caused many casualties and huge economic losses.The research status of reservoir landslide was systematically reviewed in this paper.It was generally believe by scholars that the periodic change of reservoir water level"rise-fall"was the main cause of reservoir landslide,and rock softening,buoyancy and dynamic water pressure were the action modes of disaster.How to reveal the mechanism of landslide deformation and failure under the coupling effect of rainfall and reservoir water level change,how to describe the complex behavior of landslide and surge,and how to carry out the early treatment of reservoir landslide were the key problems faced by reservoir landslide research,and also the key and difficult point.Looking forward to the future,three research directions which need to be further studied were put forward,including the complex disaster mechanism and stability evaluation of reservoir landslide,the simulation and prediction of landslide surge disaster chain,and the early prevention and control of rock mass deterioration in the subsidence area.
