| 摘 要： | 为使地下水库在丰水季节获得足够补给,利用Visual Modflow 软件,在分析地下水库水文地质条件的基础上,概化出该区水文地质概念模型,运用准三维地下水水流模型,通过有限差分方法对地下水库的地下水系统进行了模拟,拟合结果表明, 地下水位的计算值与实测值拟合程度较好,模拟出的地下水流场与实际情况基本一致.利用校正好的模型,分析了橡胶坝渗漏补给的动态变化规律,并针对橡胶坝的补给,通过数值模拟探讨了坝内蓄水因工业开采而激发的渗漏补给量.结果显示,橡胶坝的渗漏补给量在枯水期（2～5月份）逐渐增大,而在平水期（9～12月份）逐渐减小;激发补给量与激发开采量的比值呈现上升趋势,同时随着激增补给量的迅速增大,激发补给量与开采增加量的比值随工业开采量的增加而逐渐增大,这说明傍橡胶坝取水可使更多的地表水入渗补充地下水,从而有效地提高水资源的利用率.

| Abstract: | In recent years, many barrages have been founded in the Dagu River, which greatly change the conditions of the exploitation and supply of ground water. On the basis of analyzing the hydrogeological conditions and the water resource utilization of groundwater reservoirs, a quasi-three-dimensional groundwater flow model is built to simulate the groundwater flow through the finite-difference method using Visual Modflow software. The research region is divided into eleven parts after analyzing the hydrogeological conditions. After calibrating and adjusting the parameters using measured data, the calibrated model reflects the actual conditions very well. Using the model, this paper analyzes the recharge capacity of the Rubber Dam for groundwater storage. The results are as follows: (1) the amount of supplemental recharge of the Rubber Dam gradually increases from February to May but decreases gradually from September to December, (2) the ratio of induced recharge to induced withdraw shows an upward trend. Therefore it can be concluded that municipal withdraw near a Rubber Dam will stimulate more surface water to become ground water to ensure the sustainable development of groundwater reservoirs. |
