Generalization of Aquifer Group by Cumulative Transmissivity Method
-
摘要: 地下水流系统理论和数值模拟技术分别是水文地质学的基本理论和技术方法，含水岩组的概化是地下水流系统分析和地下水数值模拟的重要基础，直接影响着数值模拟和水流系统分析的精度和可信度.为提高含水岩组概化的精度和可信度，提出一种含水岩组概化的新方法，即累积导水系数法.依据岩层厚度与渗透系数乘积累积值随深度的变化，以及水文地质剖面岩性分布的整体特征，概化含水介质结构.以玛纳斯河流域为例，应用该方法概化流域内的岩性剖面，结合GMS软件中TINS模块构建水文地质结构模型.结果表明，应用该方法概化后的含水层结构具有较好的合理性和仿真性，建立的三维模型很好地显示了研究区含水介质的空间展布特征，为建立地下水流模型奠定了良好的基础.Abstract: Groundwater flow system theory and numerical simulation technique are foundamentals in hydrogeology. Generalizing aquifer group is an important foundation for groundwater flow system analysis and numerical simulation, which directly affects the accuracy and the reliability of the simulation results. This paper proposes a new method named cumulative transmissivity to generalize aquifer group, aiming at improving the generalization accuracy and reliability. The new method is characterized by aquifer structure based on the changes of the accumulated transmissivity (product of hydraulic conductivity and its thickness) with depth and the integral characteristics of the hydrogeological profile. A case study in the Manas River basin is presented in this paper. Based on the generalization, a hydrogeological structure model is built using the GMS software and its TINS module. The results indicate that the aquifer structures generalized using this method have a high rationality and fidelity. The 3D model well displays the spatial distribution of the aquifers and auitards in the study area and provides a good foundation for groundwater flow model.
