摘　　要：“开口型”隐伏岩溶洞穴的发育受构造裂隙控制，而构造裂隙发育又与一定地质历史时期的构造应力作用有关。根据这一思路，作者通过构造应力场的数值模拟来研究水城盆地的“开口型”岩溶洞穴，取得了明显效果。The development of “open form” blind karst cave is under the control of tectonic cracks,and the development of the teetonic cracks is dependent on the tectonic stress action during specified geological historical period.According to which,author discussed “open form” karst cave in the Shuicheng basin by numerical simulation of tectonic stress field and the reliable and effective result was obtained.At the same time,a new kind of analysis method about this problem is set up.
