| Abstract: | 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. |
