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.
Groundwater flow system theory and numerical simulation technology are the basic theories and technical methods of hydrogeology respectively. The generalization of aquifer group is an important foundation for groundwater flow system analysis and numerical simulation of groundwater, which directly affects the accuracy of numerical simulation and flow system analysis And credible degree.In order to improve the accuracy and credibility of the generalization of aquifers, a new method for the generalization of aquifers is proposed, namely the cumulative conductivity coefficient method.According to the relationship between the product of the product of the product of the thickness and the permeability coefficient And the general characteristics of the lithologic distribution of the hydrogeological section, and to generalize the structure of the aquifer.With the Manas River basin as an example, this method is used to generalize the lithological profile in the basin and to construct the hydrogeological structure by combining the TINS module in the GMS software The results show that the generalized aquifer structure with this method has good rationality and simulation, and the established three-dimensional model shows the spatial distribution characteristics of the aqueous medium in the study area well, laying a foundation for establishing the groundwater flow model A good foundation.
