数值模拟法在西龙河峄山断层带岩溶水允许开采量评价中的应用

Application of numerical modeling in permissive karst water yield assessment in fault zone in Yishan along Xilong River

在研究西龙河峄山断层带水源地地下岩溶水系统特征的基础上,成功建立了符合该水源地实际地下水流场的数值模型,对地下水位动态变化进行模拟和预测,进而对岩溶水允许开采量进行了评价。最后得出的结论是该水源地允许开采量定为2.8万m3/d是绝对可行的。

Based on the karst groundwater system characters of the fault zone water source site in Yishan along Xilong River, the authors established the numerical model for real flow field of karst groundwater of the water source site, in order to simulate and forecast the groundwater level dynamic variation, and then carried out the assessment of the permissive karst water exploitation yield. It was concluded that a yield of 28 000m3/d was feasible for the permissive karst water exploitation yield.
