为了满足实际生产需要,论文选择徐州市张集水源地裂隙岩溶水资源评价与研究为核心内容,在总体结构上可分为两部分: 论文第一部分包括前六章,它以徐州市张集水源地裂隙岩溶水三维数值模拟为中心内容:在实地调查以及阅读分析相关资料的基础上,概要总结和阐述了研究区的自然地理、地质概况和水文地质条件,建立了研究区水文地质概念模型;在水文地质概念模型的基础上,进一步建立了研究区非均质各向异性三维非稳定流数学模型,并利用等参有限元技术进行求解。同时研究了用数值法进行地下水资源评价时群孔抽水试验的要求和工作方法。本文将等参有限元三维流模型应用于我国北方裂隙岩溶区地下水资源评价,并将优势流概念推广到裂隙岩溶介质,结合优势结构面控水分析与地质分析,对渗透系数参数分区进行优化,然后利用群孔抽水试验资料及其后丰水期资料进行模型拟合校正,同时采用多种开采方案进行预报、评价,最终确定水源地开采方案和允许开采量,为水源地投产提供了必要依据。 论文第二部分包括后三章,它是对与地下水流数学模型相关问题而进行的理论方法探讨或实验研究。其中包括模型输入项大气降水量的预报、地下水代谢方程的推导以及潜水蒸发极限埋深的实验研究等。通过理论分析与实验研究,得出主要结论如下:(1)论文 In order to meet the needs of actual production, the paper chooses the evaluation and research of fractured karst water resources in Zhangjiu water source of Xuzhou as the core content. The first part of the dissertation consists of the first six chapters. It takes Zhangji water source The three-dimensional numerical simulation of fissure karst water is the core content: Based on the field survey and reading analysis, the paper summarizes and summarizes the natural geography, geology and hydrogeological conditions of the study area and establishes the conceptual model of hydrogeology in the study area; Based on the conceptual model of hydrogeology, a three-dimensional non-isotropic anisotropic flow mathematical model of the study area is further established and solved by using the isoparametric finite element method. At the same time, the requirements and working methods of group hole pumping test when using numerical method to evaluate groundwater resource are studied. In this paper, the isoparametric finite element method was applied to the groundwater resource assessment of the fractured karst area in northern China. The concept of the dominant flow was extended to the fractured karst medium. Based on the controllable water and geological analysis of the dominating structure surface, the parameters of the permeability coefficient were optimized, Then, using the data of group hole pumping test and subsequent wet season data, the model fitting and correction are carried out. At the same time, a variety of mining schemes are used for forecasting and evaluating, finally determining the water source mining scheme and allowable mining volume, which provides the necessary basis for water source production . The second part of the dissertation consists of the last three chapters, which are theoretical methods or experimental studies on the problems related to groundwater flow mathematical models. Including the prediction of atmospheric precipitation of model input, the derivation of groundwater metabolic equation, and the experimental study of submerged evaporation limit depth. Through theoretical analysis and experimental research, the main conclusions are as follows: (1) Thesis
