【摘要】：济南市因泉水众多而闻名于世，济南泉水是宝贵的自然文化遗产，具有较为突出的全球性价值。随着城市化的加速发展，岩溶地下水的开采量持续加大，导致济南地下水位下降，产生泉水停喷等一系列水环境问题。本文在对济南地区地质、水文地质等条件的调研分析的基础上，探讨了济南市地下水适宜回灌地点、回灌水源以及回灌方式，利用地下水数值模拟软件GMS建立济南市地下水数值模型，设计地下水回灌量分配方案，经模拟预报，验证回灌方案可行性。并且从回灌水量、水质以及库容不确定性三方面对联合调蓄进行了风险性评价。研究成果对保护济南的泉水、合理开发利用水资的具有重要意义。本论文主要结论如下：（1）分析选取了济南市调蓄补源适宜回灌地点。根据下渗能力，将回灌地段分为自然下渗带和人工回灌带。济南泉域24个强渗漏带中，14个近自然状态渗漏带属于自然下渗带，10个已经或者正在进行开发建设的渗漏带属于人工回灌带。本文选定玉符河渴马至罗而庄段、北沙河东风水库至崮山镇河段、兴济河兴隆至土屋段、广场东沟、泉泸~钱家庄沟为地下水优先回灌补源地点。（2）分析确定了济南市地表水与地下水联合调蓄的适宜水源。确定地表水与地下水联合调蓄主要水源有大气降水、黄河水、南水北调的长江水以及卧虎山水库、锦绣川水库、玉清湖水库等各大水库。（3）提出了调蓄补源的工程措施。综合考虑地下水人工回灌的条件，并结合济南市具体水文地质条件和实际情况，得出两条调蓄补源工程布置原则：利用自然渗透能力补给地下水和蓄水入渗与城市防洪相结合。济南地下水回灌补给采用地面入渗法和管井注入法两种方式。地面入渗采用线状补给、水库塘坝入渗和渗池入渗等方式。管井注入法采用立式排水，设置渗井。（4）得出了适宜的回灌方案。通过计算调蓄区内可调蓄容量，得出泉域直接补给区的年水位变幅带储存量为12904.36万m3。设计四个回灌量分配方案，经模型模拟表明：多年平均降雨量时，玉符河渴马到罗而庄段、崮山河坝至北沙河东风水库河段、兴济河兴隆至土屋段、广场东沟、泉泸~钱家庄沟适宜保泉回灌量分别为16.7万m3/d、7.3万m3/d、2万m3/d、1.4万m3/d、2.6万m3/d；降水保证率为75%时，，玉符河渴马到罗而庄段、北沙河东风水库至崮山镇河段、兴济河兴隆至土屋段、广场东沟、泉泸~钱家庄沟适宜保泉回灌量分别为17.5万m3/d、8万m3/d、2.6万m3/d、2万m3/d、3.5万m3/d。（5）进行风险性评价，分析出了地表水与地下水联合调蓄水量、调蓄水质的情况以及库容不确定性。分别从调蓄水量、调蓄水质以及库容不确定性三个方面评价调蓄风险性。经分析评价，济南市卧虎山等水库水量丰富，且有黄河水和南水北调的长江水可作为调蓄水源，地下水回灌水源水量可得到充分保证；调蓄水源基本符合地下水回灌水源的水质标准，但当设立回灌井回灌时，需控制源水的混浊度和细菌指标，配备必要的水质净化和沉淀设施；利用蒙特卡罗法分析库容不确定性，得知给水度均方差对库容影响较大，均值的变化对库容均方差影响不大。
[Abstract]:Ji'nan City, due to large number of springs is famous in the world, Ji'nan spring water is a precious natural and cultural heritage, is a global value more prominent. With the accelerated development of the city, the exploitation of karst groundwater in Ji'nan continued to increase, decline of groundwater level from spring water stopped a series of water environmental problems. Based on the geological area of Ji'nan investigation and analysis, based on the hydrogeological conditions of Ji'nan City, groundwater recharge suitable locations, recharge and recharge, groundwater numerical simulation software GMS to establish the value model of groundwater in Ji'nan City, the design of groundwater recharge amount allocation scheme, the simulation forecast, verify the feasibility of the program. And irrigation recharge the water from the water back, as well as three capacity uncertainty on the combined operation of risk assessment. The research results on the protection of Ji'nan water, water resources with reasonable development It is of great significance. The main conclusions of this paper are as follows:
(1) analysis of the selection of Ji'nan storage recharge recharge suitable place. According to the infiltration capacity, the recharge area is divided into the natural infiltration zone and artificial recharge zone. Ji'nan springcatchments 24 strong leakage band in 14 near natural state seepage zone belongs to the natural infiltration, 10 have leakage or is the development and construction of the zone belongs to the artificial recharge zone. This paper selected Yufuhe River thirsty horse to Luo Zhuang, North Shahe Dongfeng reservoir to Gushan Town River, Xing Ji river is to Tsuchiya, square Donggou, Quan Lu Qian Jia Zhuang Gou ~ for groundwater recharge priority locations.
(2) analysis and determination of suitable water sources for joint storage of surface water and groundwater in Ji'nan. It is determined that the main sources of surface water and groundwater joint storage include atmospheric precipitation, the Yellow River water, Yangtze River water from south to North Water Diversion, and "hushushan reservoir", "Jinxiu Chuan reservoir", "Yuqing lake reservoir" and other reservoirs.
(3) proposed measures to supplement the source storage project. Considering the artificial recharge of groundwater conditions, combined with the specific hydrogeological conditions and the actual situation of Ji'nan City, the two water source supplement project layout principle: the use of natural groundwater recharge and water infiltration capacity and infiltration combined with the city flood control and groundwater recharge in Ji'nan. Recharge by surface infiltration method and tube wells injection method in two ways. The linear ground infiltration recharge, reservoir infiltration and infiltration infiltration etc.. Wells injection method with vertical drainage, seepage well set.
(4) the opuimum recharge scheme. By calculating the storage area within the storage capacity, the annual water level of spring field direct recharge area with a storage capacity of 129 million 43 thousand and 600 m3. design four recharge volume allocation scheme by the model simulation results show that the average rainfall years, Yufuhe River thirsty horse to Luo Zhuang section, Gushan dam to the north of Shahe Dongfeng Reservoir River, Xing Ji river is to Tsuchiya, square Donggou, Quan Lu Qian Jia Zhuang Gou hoizumi ~ suitable recharge volume were 167 thousand m3/d, 73 thousand m3/d, 20 thousand m3/d, 14 thousand m3/d, 26 thousand m3/d; rainfall guaranteed rate of 75%, Yufuhe River thirsty horse to Luo Zhuang, North Shahe Dongfeng reservoir to Gushan Town River, Xing Ji river is to Tsuchiya, square Donggou, Quan Lu Qian Jia Zhuang Gou hoizumi ~ suitable recharge volume were 175 thousand m3/d, 80 thousand m3/d, 26 thousand m3/d, 20 thousand m3/d, 35 thousand m3/d.
(5) risk assessment, analysis of the content of conjunctive regulation of surface water and groundwater, water quality and storage capacity uncertainty. Separately from the storage of water, water storage capacity and the uncertainty of the three aspects of risk evaluation. Regulation of Wohushan reservoir in Ji'nan city and other water rich, and water in the Yellow River and the diversion of the Yangtze River water as water sources, groundwater recharge water source water can be fully guaranteed; storage water accords with the standard of water quality of groundwater recharge, but when the establishment of recharge well irrigation, control source water turbidity and bacteria index, equipped with necessary water purification and sedimentation facilities; analysis of reservoir uncertainty by using Monte Carlo method, that the water level variance on the capacity of a greater impact, the change of the mean variance of the capacity is not affected.
