摘要
本文以湖北省兴山县王家岭滑坡前缘变形体为例,对膨胀土类滑坡的形成条件和成因机制进行了分析,认为大气降雨和良好的临空条件是构成该滑坡变形的外因,膨胀土亲水性强、遇水易软化的性状,使滑带土抗剪强度衰减是其内因,其分析成果可供类似工程参考。
Taking the example of front-edge deformation body of Wangjialing landslide of Xingshan County, Hubei Province, this paper analyses the formation conditions and genetic mechanism of dilative soil landslides and considers that the atmospheric precipitation and good air-touching conditions are the external factors of the landslide deformation while the strong water affinity and the property of becoming soft when it meets water to weaken the shearing strength of the landslide belt soil are the internal factors. The analytical results can be used for reference for the similar project.
