沿接触面滑动的条件及冲积层中移动传播方向

Study on the Conditions of Strata Movement along Weak Planes and Its Direction in Alluvia

表土层较厚时弱面滑动引起的表土层移动方向是一个尚未解决的问题．根据某煤矿附近农房的损害实际资料及该矿的地质、采矿条件，通过有限元数值模拟，分析了开采影响下岩层沿薄弱层面滑动的条件及表土层中移动传播的方向．

The direction of strata movement in thick alluvia is an unresolved problem. By using FEM digital modeling, based on house damage induced by coal mining and its geology and mining conditions near a coal mine, the conditions of strata movement along weak planes and its direction in alluvia due to coal mining are analysed.
