| 摘 要： | 通过大量现场调查、室内外试验及计算等研究的基础上,揭示了只要具有一定滑体厚度的滑带土,沿滑面具有强度再生效应。利用该观点,结合滑坡破坏特征,滑带土的物质组成及其赋存环境条件,对滑面强度参数的选取及其对稳定性的影响进行了详细探讨,该研究为滑坡滑面强度参数的选取提供了重要的理论依据。

| Abstract: | On the basis of the field investigation, laboratory and in-situ tests and calculations, authors discovered that strength restoration effect along slide planes would happen if the thickness of upper sliding mass reaches a certain value. In this opinion, together with failure property, grain composition, and the environmental condition that slip zone soil existed, the selection of strength parameters along slide planes was detailed studied. The stability of the landslide was also analyzed and evaluated. The method provides an important theoretical basis for choosing and evaluating strength parameters of slip zone soil. |
