| 摘 要： | 天台滑坡是在平缓斜坡和平缓岩层区发生的特大型土质滑坡，以多级分块滑动为主要特点。滑体的水平位移量前部最大，向后部逐渐减小。根据滑坡体上槽、脊相间的复杂的台阶式地形概括出5种滑坡次级变形模式，分析了滑坡产生多级分块滑动的主要条件，建立了水压力推动滑坡产生分块滑动的成因模式。

| Abstract: | The Tiantai Landslide is a soil one of extra large-scale occurred in the region of gentle slope and gently dipping formation. The main character is slipping in multi-stage and mass-by-mass. It＇s horizontal displacement is the largist in the front and reducing towards the back. Five secondary deforming patterns are summarized according to the varied platform topography with troughs and ridges, the essential conditions producing the multi-stage and mass-by-mass sliding is analyzed, and genetic model forming the mass-by-mass sliding by water pressure is established. |
