| 摘 要： | 贵州省关岭县2010年6月28日发生的大寨高速远程滑坡是2010年和强降雨有关的具有代表性的滑坡之一。在发生暴雨期间,在雨水的软化作用下关岭大寨滑坡岩体强度迅速下降;同时滑坡后缘拉裂隙产生的静水推力以及滑动面产生的浮托力对于滑坡稳定性的下降起到了重大影响。运用3DEC建立关岭大寨滑坡三维模型,结合强度折减法对滑坡进行模拟,得出暴雨发生前和发生后的滑坡安全系数并对滑坡失稳过程进行分析,证明暴雨是发生此次地质灾害的关键诱因。

| Abstract: | Guizhou province GuanLing Dazhai high-speed long-runout landslide in the June 28 of isSone of the typical landslideSthat related to rainstorm in 2010. The strength of Dazhai landslide which is given priority to with mudstone decreased rapidly under the softening action of the heavy rain. Hydrostatic pressure of trailing edge and buoyancy of sliding surface for the stability of the landslide decline has played a significant impact. Combined with strength reduction method and usis 3DEC for simulating Dazhai landslide.Landslide safety coefficient before and afte rainstorm are obtained and analysises the instability of the landslide. |
