补给带法在基岩裂隙水可开采量计算中的应用

Application of recharge zone method to calculation of allowable withdrawal of bedrock fissure water

针对基岩裂隙水赋存介质的不均匀性及其可开采量计算中水文地质参数的不确定性,采用补给带法对某矿泉水厂开采区域的基岩裂隙水可开采量进行计算;在水文地质调查的基础上,采用可开采系数法对该区域基岩裂隙水可开采量进行计算,并与补给带法计算结果进行对比。结果表明:两者计算结果十分接近;补给带法较为简单,避免了基岩水文地质参数的不确定性造成的计算结果的不确定性,可以作为基岩裂隙水可开采量计算的方法之一。

To avoid the influence of the inhomogeneity of the medium containing bedrock fissure water and the uncertainty of hydrogeological parameters, the recharge zone method was used to calculate the allowable withdrawal of the bedrock fissure water in a mineral water factory. Based on hydrogeological investigation, the allowable withdrawal coefficient method was used to calculate the allowable withdrawal of the bedrock fissure water in the study area, and the results of this method were compared with those obtained with the recharge zone method. It was shown that the results from both methods were almost consistent. The recharge zone method is simpler, and it can avoid the uncertainty of calculated results caused by the uncertainty of hydrogeological parameters, which validates its application to the precise calculation of the allowable withdrawal of bedrock fissure water.
