摘要
滑坡-泥石流地质灾害链具有突发性、难以监测等特点,近年来引起学者和工程师的广泛关注。元阳梯田滑坡-泥石流灾害链试验目的是通过设置降雨工况,持续记录元阳梯田室内模拟模型滑坡-泥石流灾害链形成发展和演化过程,并记录实时体积含水率、基质吸力、土压力和孔隙水压力变化规律等相关信息,揭示滑坡-泥石流灾害链形成演化作用机理和雨量阈值。研究方式主要为室内模型模拟试验,通过模拟野外降雨诱发地质灾害的过程,揭示元阳梯田滑坡-泥石流地质灾害链形成机理及时空演化规律。
The landslide-debris flow geological hazard chain has the characteristics of sudden occurrence and difficult to monitor,which has aroused the research focus of scholars and engineers in recent years.The purpose of the landslide debris flow disaster chain test in Yuanyang Terrace is to continuously record the formation,development and evolution process of landslide debris flow disaster chain in the indoor simulation model of Yuanyang Terrace by setting rainfall conditions,and record relevant information such as real-time volumetric water content,matric suction,soil pressure and pore water pressure,so as to reveal the formation and evolution mechanism of landslide debris flow disaster chain and rainfall threshold.The research method is mainly indoor model simulation experiment,through simulating the process of field rainfall-induced geological disasters,to reveal the formation mechanism and spatio-temporal evolution law of the landslide and debris flow geological disaster chain in Yuanyang terrace.
