该文在分析济宁市地面沉降特征的基础上，建立了一个地下水一地面沉降耦合模型，用于模拟和预测在不同开采条件下含水层中地下水头的分布和地面沉降量。计算结果表明，耦合模型计算结果与实测值拟合很好。
Based on the analysis of land subsidence characteristics in Jining City, a groundwater-surface subsidence coupling model was established to simulate and predict the distribution of aquifer head and ground subsidence in aquifer under different mining conditions. The calculation results show that the coupling model calculation results are well fitted with the measured values.
