摘要
本文以天水市孟家山滑坡为例 ,分析了黄土 -红层接触面滑坡的发育特征 ,运用相似材料物理模拟试验 ,研究了“坡体蠕动—后缘拉裂—滑带由中部向两侧发展—剪出口形成—坡体突滑”
The paper selects the Tianshui Mengjiashan landslide as a case to study this kind of landslide where sliding surface is between loess and Negecene red mudstone. The deformation mechanism has been studied by physical simulation test. The study result presents that the geological process of the landslide form is slope creeping, cracking at the back of the slope, sliding zone forming, appearance of the sliding zone's exit,and then slope sliding. This study is contributed to forecast this type landslide.
