岩溶塌陷是山东省近年来濒发的主要地质灾害之一,主要分布于泰安、枣庄、临沂、莱芜等覆盖型岩溶发育区,其发展、发生主要受岩溶水不合理开采所致,水位是影响岩溶塌陷的重要因素。本文以临沂市城区的岩溶塌陷为例来探讨岩溶塌陷预警预报思路,首先是在完善的监测网络基础上,建立预警模型,通过水文地质模型预测可行的地下水开采方案,并模拟城区一带的岩溶塌陷区水位的变化趋势,人为控制地下水动力场,进而建立岩溶塌陷动力预警预报系统,可为减少或避免该灾害的发生及其防治提供科学依据。
Karst collapse is one of the major geological disasters endangered in recent years in Shandong Province. It mainly distributes in cover karst development areas such as Tai’an, Zaozhuang, Linyi and Laiwu. The development and occurrence of karst collapse are mainly caused by the unreasonable exploitation of karst water. Karst collapse of the important factors. In this paper, the karst collapse in Linyi city is taken as an example to explore the idea of karst collapse early warning and forecasting. The first is to establish an early warning model based on a sound monitoring network, predict the feasible groundwater exploitation program by hydrogeological model and simulate the karst collapse in the urban area The change trend of the water level in the district and artificially control the groundwater dynamic field and then establish the dynamic early warning and forecasting system of karst collapse can provide a scientific basis for reducing or avoiding the occurrence of the disaster and its prevention and control.
