基于地下水调控的沧州市地面沉降防治模拟研究

Modeling land subsidence prevention based on groundwater regulation in Cangzhou

地下水的不合理开采是引发地面沉降的关键因素。文章根据研究区水文地质及工程地质条件,对含水层和弱透水层进行概化,运用Modflow软件建立了研究区的地下水流模型和地面沉降土水耦合模型。针对可采用的地下水调控模拟方案对沧州市的地面沉降发展趋势做出预测,为今后合理开采地下水,控制地面沉降发展提供技术依据。

Uncontrolled exploitation of groundwater is one of the key factors causing land subsidence. Based on measurements of the hydrogeological and engineering geological conditions in the study area, this article develops a generalized aquifer and aquitard model using the Modlfow software, an established model that combines groundwater lfow and soil-water interactions to model ground settlement. Using this model, we make predictions of land subsidence under various simulated regulatory schemes to provide guidance for the managed exploitation of groundwater and prevention of land subsidence.
