库水浸泡后滑坡体中水分布的实验研究

EXPERIMENTAL STUDY ON WATER DISTRIBUTION IN LANDSLIDE WITH RESERVOIR TABLE CHANGED

  • 摘要: 建立了室内模拟库水浸泡后滑坡体内水润湿的渗流实验装置,根据清江茅坪滑坡的地形、地貌以及岩土混合比例,填制了岩土体实验模型. 模拟了水位在涨至模拟坡体凌空面一半高度和水位漫过凌空面达到第一平台高度时,坡体内的水分布情况. 在水位降落实验过程中,岩土体部分失稳,证明了润湿滞后在降水期滑坡中起主要作用.

     

    Abstract: The experimental equipment is established forsimulating water distribution in landslide with reservoir table changed. Thelaboratory model is made based on the shape, geometric characters andsoil-rock ratio of Maoping slide. The water distributions in the simulatedslide are simulated with water table at the half height of the soaredinterface and the height of the first platform. When the reservoir tabledrops down in the experiment, a part of the slide fails. The results showthat wetting lagging is the main factor of slide failure during thereservoir table drop-down.
