摘要
岩溶塌陷是近年来频发的主要地质灾害类型之一,其发生、发展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。文章以临沂市城区岩溶塌陷为例,探讨在建立完善的监测网络基础上,通过水文地质模型模拟城区一带的岩溶塌陷区水位的变化趋势,预测分析可行的地下水开采方案,建立起完整的岩溶塌陷动力预警系统,为减少或避免岩溶塌陷的发生提供了科学依据,也为同类地质灾害的监测、预警、预防提供了借鉴模式。
Karst collapse is a main geological hazard happening frequently in recent years as a resuh of unreasonable exploitation of karst groundwater. Groundwater level is an important factor affecting karst collapse. An early-waming system structure of karst collapse in the Linyi urban zone is established in this article. The early-warning model is based on a developed monitoring net. It can forecast the feasible program of exploitation of the groundwater, imitate the trend of water levels in the karst collapse zone of the urban area, and construct an early-waming system by monitoring. The early-warning system provides a scientific basis for the prevention and eontrol of karst collapse, especially for reducing and avoiding the occurrence of karst collapse. It also provides a reference pattem for puttirig up availability exploration on monito.ring, early-warning and prevention of the similar geological hazards.
