外调水支持下淮北市岩溶水开采方案研究

Study on karst water exploitation scheme in Huaibei City supported by external water diversion project

文章利用水位自回归与多元回归相耦合模型,建立了与开采量、降水量相关的水位递推方程;在地下水水位不低于设定水位的约束下,设计岩溶水合理开采量,讨论了外调水支持下的岩溶水开采策略,并对开采量与临界水位的动态关系进行了研究。结果表明,利用水位递推方程可以计算临界水位控制条件下的合理开采量,当采用7.5 m作为管理控制的临界水位,开采强度可控制在22.05×10^(4) m^(3)/d左右,可为未来外调水支持下淮北市岩溶水开采方案的制定提供一定的参考依据。

This study utilizes a coupled model of water level autoregression and multiple regression to establish a water level recursive equation related to exploitation volume and precipitation for the karst water system.Under the constraint that the groundwater level does not fall below a set level,a rational exploitation volume for karst water is designed and the exploitation strategy of karst water is discussed supported by external water diversion.Additionally,the dynamic relationship between exploitation volume and critical water level is studied.The results indicate that the water level recursive equation can be used to calculate the rational exploitation volume under the critical water level control condition.When adopting 7.5 m as the critical management water level,the exploitation intensity can be controlled at approximately 22.05×10^(4) m^(3)/d.These findings provide a reference for the formulation of future karst water exploitation schemes in Huaibei City with the support of external water diversion.
