摘要
分析了岩溶塌陷演化过程中物理力学上的水 土 岩相互作用 ,并对作用模式进行了探讨。分析结果表明岩溶塌陷的发育和水 土 岩相互作用密不可分 ,塌陷的物质载体是盖层土体和岩层的顶板 ,而地下水赋存于岩土体内 ,地下水和岩土体之间存在着复杂的物理力学、化学作用 ,土体和岩体之间也存在着应力传递和物质传输作用 ;反之 ,岩土体结构和稳定状态的变化也会改变地下水的渗流运动状态 ,从而又反过来影响岩土体的结构和稳定状态 。
The physical and mechanical interaction of groundwater soil rock mass in karst collapse evolution is discussed elaborately and a coupling mode is established and studied. Analysis results show that the evolution of karst collapses connects closely with the coupling interaction of groundwater soil rock mass. The material carrier of collapses is the covering soil mass and the rock's top layer, and the groundwater is stored in the soil rock mass. Complicated physical, chemical and mechanical interactions exist between the groundwater and the soil rock mass, while stress and mass transfer exists between soil and rock masses. On the other hand, the change in soil rock mass's structure and stability will influence groundwater's movement, and the change of groundwater's movement influences soil and rock mass's structure and stability state in reverse, until the appearance of karst collapses.
