| 摘 要： | 科学有效的地下水资源评价是可持续开发地下水资源的关键,其中地下水资源可开采量的评价是地下水资源评价的核心内容。该文在对枣庄市台儿庄区小龚庄水源地水文地质条件、岩溶塌陷发育情况等进行详细分析的基础上,采用开采试验法对小龚庄水源地岩溶地下水允许开采量进行了计算,计算结果为11354m~3/d。根据已发生岩溶塌陷情况,设定岩溶塌陷预警水位,利用非稳定流Theis公式计算了安全开采量范围在11187～13150m~3/d之间,对开采试验法计算结果进一步进行评价。根据评价结果最终确定以11354m~3/d作为小龚庄水源地的允许开采量是可靠的,可以保证水源地最大限度的开采地下水资源,同时又保证水源地运行时不易引发岩溶塌陷的环境地质问题。该方法为同类型水源地地下水允许开采量的计算评价提供了一定的借鉴。

| Abstract: | Scientific and effective evaluation of groundwater resources is the key to sustainable development of groundwater resources, and the evaluation of exploitable groundwater resources is the core content of groundwater resources evaluation. Based on detailed analysis of hydrogeological conditions and karst collapse development of Xiaogongzhuang water source area in Taierzhuang district of Zaozhuang city, the allowable exploitation of karst groundwater in Xiaogongzhuang water source area is calculated by using mining test method. The calculation result is 11354m3/d. According to already happened karst collapse, the early warning water level of karst collapse has been set. The safe mining yield has been calculated by Theis formula. The unsteady flow is 11187~13150m3/d. The calculation results have been evaluated furtherly by using mining test method. According to the evaluation results, it is determined that the allowable exploitation rate of Xiaogongzhuang water source area is reliable. It can ensure the maximum exploitation of groundwater resources in the water source area, and ensure that the environmental geological problems of karst collapse are not easily caused when the water source area runs. This method provides some references for the calculation and evaluation of groundwater allowable exploitation in the same type of water source area. |
