摘要
岩溶塌陷是近年来濒发的主要地质灾害。其发生、发展、主要受岩溶水不合理开采所致。地下水位是影响岩溶塌陷的重要因素。论文以临沂市城区岩溶塌陷为例,在完善的监测网络基础上,建立了地下水数值模型,预测了可行的地下水开采方案,并模拟城区岩溶塌陷区水位与基岩顶板的变化关系。研究建立了岩溶塌陷动力预警系统。该系统为减少或避免岩溶塌陷的发生及防治提供科学依据。
Karst collapse is the main geohazard, happening frequently in recent years, which is resulted from unreasonable exploiting karst groundwater. So water level is an important faction. In this article the authors reach the early-warning system structure of karst collapse in Linyi city zone. Groundwater numerical simulation has been built up on basis of developed monitoring net. It forecasts the feasible program of exploitation of the groundwater, imitates the relation of variation between water level and bedrock roof in the karst collapse zone of the urban area, and constructs a system of earlywarning by monitoring. The early-warning system provides a science basis for prevention and cure of karst collapse, especially to reduce and avoid being happened on karst collapse.
