利用黄河水回灌某漏斗区浅层地下水条件分析

摘要

Based on the study of hydrogeological characteristics and storage space within the distribution of depression cone of groundwater leve about Huaxian County-Qingfeng-Puyang-Neihuang-Nanle, this paper discussed the Yellow River and its tributaries, such as surface wa-ter, by natural river channels and artificial impoundment surface water, recharging the disposal well and other methods, and the feasibility of regulating and storaging and recharging the local groundwater.The analysis shows that the permeability of surface lithology is strong in funnel areas,the construction technology of changing vertical tube well to a horizontal tube well is mature, so the conditions are feasible to supply the groundwater in funnel areas through regulation and recirculation by using the Yellow River water.It can ease the situation of water shortage in the area by regulation,and also control the groundwater cone of depression become deepper, expand and improve the ecological environment, so it can prevent and treat land subsidence, desertification, land crack seffectively.%在研究滑县—内黄—清丰—濮阳—南乐地下水降落漏斗分布范围内水文地质特征和调蓄空间的基础上,探讨利用黄河及其支流等地表水源,通过天然河道、人工渠道、回灌渗井等回灌调蓄补给当地地下水的可行性. 通过分析认为,漏斗区地表岩性渗透性强,垂直变水平管井施工技术成熟,因此,利用黄河水回灌调蓄漏斗区地下水经济合理、技术可行. 通过调蓄可以缓解区内水资源紧缺的形势,控制地下水降落漏斗的加深、扩大,改善生态环境,有效防止地面沉降、土地沙化、地裂缝的发生.
