摘要
姜堰市地处长江北部三角洲沉积区与里下河沉积区间的过渡带,孔隙承压地下水分布复杂,南北差异明显,地下水资源评价难度大。对研究区复杂孔隙承压地下水系统进行了三维数值模拟,并在模型识别、验证的基础上,确定出符合水位控制要求的可开采资源量及优化开采布局。结果证明,通过三维数值模型进行地下水资源评价,既能客观再现复杂的水文地质结构和水文地质条件,同时也有助于对地下水资源进行科学有效管理。
Located in transition region between Yangtze River North Delta deposition area and Lixia River deposition area, the distribution of pore＇confined groundwater in Jiangyan is complex, and its north-south differences are obvious, so the groundwater resource is difficult to evaluate. A three-dimensional numerical model is built for the groundwater system of pore confined aquifer in Jiangyan. Based on the recognition and verification of this model, the exploitable amount of groundwater and the optimized exploitation pattern are established for control requirement of the waterlevel in the each aquifer. The results prove that the groundwater resources evaluation with three-dimensional numerical model, not only reproduces the complex hydrology structure and condition of aquifers, but also contributes to the scientific and effective management of groundwater resources.
