| 摘 要： | 在20世纪80年代以来，莱芜市泉河地区发生多起岩溶塌陷，而且岩溶塌陷的发生具有突发性、重复性。在已有研究成果的基础上通过现场调查，系统总结了莱芜市泉河地区岩溶塌陷特征，即岩溶塌陷的形成与分布在空间上具有方向性，在时间上具有阶段性与集中爆发期。岩溶塌陷发育情况、覆盖层条件和水文动态资料综合分析结果表明，莱芜市泉河地区岩溶塌陷是区内水动力条件的改变造成的。

| Abstract: | Since 1980s, karst collapse have occurred many times in Quanhe area of Laiwu city, and collapse has the characteristics of sudden and repetitive. On the basis of existing research results and through the on - site survey, characteristics of karst collapse in Quanhe area of Laiwu city have been summarized. That is the formation and distribution of karst collapse have a direction in space, and have stages and focusing outbreak in time. As showed by karst collapse development, covering layers and hydrological and dynamic data, karst collapse in this area is formed by the changes of hydrodynamic conditions. |
