【摘要】 本文分析了地下水位下降对岩溶地面塌陷的影响,认为有效应力的变化及动水压力的增加是地下水水位下降导致地面塌陷的根本原因.在该机理分析的基础上,给出了一定条件下;地下水位下降值与岩溶塌陷总数的定量关系式,并进行了一定程度的验证.更多还原

【Abstract】 The influence of ground water depression on karst collapse was studied in this paper. Depression of ground water causes the changes of effective stress and hydrodynamic pressure, that is the fundamental cause resulting in karst collapse. On the basis of mechanism analysis, the relationship between the number of karst collapse and ground water depression is presented in this paper, which is demonstrated to a certain extent.更多还原
