摘要

文中计算分析天津市平原区Ⅱ～Ⅴ含水层组典型漏斗区的漏斗面积、漏斗中心水位,根据漏斗分布,拟定了2个分层组地下水压采方案。其中,方案一的拟定仅仅依据地下漏斗分布,而方案二依据水务管理部门提出的2020年攻坚目标开采量,并综合考虑了地下漏斗分布、各乡镇的具体供给水源及用水需求,更适合实施开展。针对南水北调工程水源地和受水区的5种不同丰、枯遭遇情况,利用水文频率分析方法计算本地地表水及入境水、引滦水、引江水量,对两种压采方案进行供、需水均衡分析。构建平原区分层组的地下水数值模型,进行识别与验证,预测压采方案下各层组近、远期的地下水位分布,对比分析漏斗面积和漏斗中心水位的修复程度。结果表明,方案一的修复效果优于方案二,但方案二更易于实施。在南水北调工程通水的机遇下,研究结果为合理开发利用地下水资源、制定压采方案、修复地下漏斗提供了科学依据。
        In this paper, typical groundwater depression cone area and depth in Ⅱ～Ⅴ aquifer were calculated and analyzed. Two exploitation control plans were studied. Plan one was determined only by distribution of depression cone of each aquifer. While Plan two was worked out combining target exploration, detailed water supply and demand, and drawing well, and depression cone distribution, which is more suitable to be popularized and used. According to five kinds of wetness-dryness encounters of water received area and supply area of South-North Water Diversion Project, local surface water, inbound water, diversion water from Luanhe River and Yangtze River were calculated. Equilibrium of water supply and water demand was analyzed with these two exploitation control plans. Groundwater numerical model was established, calibrated and verified. Using it, groundwater tables of short term and long term were predicted, and repair effect of depression cone area and depth were compared. The result show that the repair effect of Plan one was better than Plan two, while Plan two is more suitable to carry out. It offers technology support for reasonably developing groundwater, making exploitation control plans and repair depression cone.
