摘要
地下水动力条件变化是导致临沂市城区岩溶塌陷的诱因和动因,通过分析岩溶区地质及水文地质条件,建立了临沂市城区岩溶地下水流数值模型,预测了2007年6月至2019年6月地下水水位时空变化过程。从流场拟合情况看,所建模型拟合效果良好,客观反映了地下水系统演化规律,可以用于岩溶塌陷预警预报,为岩溶塌陷地质灾害防治提供技术依据。
Through analysis on geological and hydrogeological conditions of karstic areas, numerical model of karstic groundwater flow is established in Linyi city, and the water level change from June 2007 to June 2019 is predicated as well. As showed by the result, it is conform with the hydrogeological conditions in research areas. Thus, it can be used to predicate karst collapse and to provide technical basis for preventing and controlling geological disasters in karst collapse areas.
