该文从地下水系统性观点出发,初步分析探讨了地下水水资源论证中存在的问题,指出目前建设项目中地下水水资源论证评价存在的不足,并以河北省玉田县城供水工程勘探阶段水资源论证为例,采用水均衡法、数值法、解析法等方法对地下水资源进行评价。建议地下水水资源论证应明确论证的阶段和前提条件,保证论证内容能够达到必要的深度;项目立项后,应在初步设计和施工图设计前继续进行水资源论证,分别达到相应精度要求,真正做到水资源管理、审批与建设项目建设程序的和谐统一。
Based on the systematic groundwater system, this paper analyzes and discusses the problems existing in groundwater water resources demonstration and points out the deficiencies of groundwater water resources demonstration in current construction projects. Based on the water resources demonstration in the water supply project of Yutian County in Hebei Province, Example, the use of water balance method, numerical method, analytical method and other methods to evaluate groundwater resources. It is suggested that the justification phase and preconditions of groundwater water resources demonstration should be ensured to ensure that the contents of demonstration can reach the necessary depths. After project establishment, water resources demonstration should continue to be carried out before preliminary design and construction drawing design, and the corresponding precision requirements should be achieved. To the water resources management, approval and construction projects in the process of building a harmonious unity.
