| 摘 要： | 在分析济宁市水文地质条件的基础上 ,对引起地面沉降诸因素进行了分析 ,并建立了地面沉降量与地下水位变幅之间的相关关系。集中过量开采地下水是引起济宁市地面沉降的主要原因。在此基础上 ,建立了准三维地下水流模型和一维地面沉降模型。通过水力联系建立地下水与地面沉降耦合数值模型 ,运用有限元法对地下水渗流场和地面沉降量进行模拟 ,并对 2 0 0 0年和 2 0 10年地面沉降进行了预测

| Abstract: | On the basis of hydrogeological conditions of Jining city, some factors of caused land subsidence were analyzed. The correlativity of land subsidence and groundwater table changes were established. It is believed that the land subsidence of Jining city is caused by excessive extraction of groundwater. 3D groundwater flow model and 1D land subsidence model were constructed. The coupling model of groundwater and land subsidence was constructed through hydraulic relationship. Groundwater flow domain and land subsidence were simulated by finite element method, and the land subsidence of study area in 2000 and 2010 were also predicted. |
