管道漏水引起黄土滑坡失稳机理研究
Study on the Instability Mechanism of Loess Landslide Caused by Pipeline Leakage
摘要
Abstract
A major geological disaster of landslide happened in Dongxiang County of Gansu Province on March 2nd ,2011 ,which threatened the safety of two thirds of the total population .The landslide survey was performed to analyze the development char‐acteristics of landslide .The moisture absorption of soil‐water characteristic curve test was conducted on the unsaturated loess , and the seepage field of landslide caused by the pipeline leakage was simulated based on the saturated and unsaturated theory . The variation of seepage field of loess landslide caused by the pipeline leakage was analyzed .Finally ,the original slope stability was compared with and the slope stability caused by the pipeline leakage ,which confirmed that the pipeline leakage induces loess landslide .关键词
