【摘要】：地下水流系統(tǒng)理論和數(shù)值模擬技術(shù)分別是水文地質(zhì)學(xué)的基本理論和技術(shù)方法,含水巖組的概化是地下水流系統(tǒng)分析和地下水?dāng)?shù)值模擬的重要基礎(chǔ),直接影響著數(shù)值模擬和水流系統(tǒng)分析的精度和可信度.為提高含水巖組概化的精度和可信度,提出一種含水巖組概化的新方法,即累積導(dǎo)水系數(shù)法.依據(jù)巖層厚度與滲透系數(shù)乘積累積值隨深度的變化,以及水文地質(zhì)剖面巖性分布的整體特征,概化含水介質(zhì)結(jié)構(gòu).以瑪納斯河流域為例,應(yīng)用該方法概化流域內(nèi)的巖性剖面,結(jié)合GMS軟件中TINS模塊構(gòu)建水文地質(zhì)結(jié)構(gòu)模型.結(jié)果表明,應(yīng)用該方法概化后的含水層結(jié)構(gòu)具有較好的合理性和仿真性,建立的三維模型很好地顯示了研究區(qū)含水介質(zhì)的空間展布特征,為建立地下水流模型奠定了良好的基礎(chǔ).
[Abstract]:The theory of groundwater flow system and numerical simulation technology are the basic theories and technical methods of hydrogeology, respectively. The generalization of water-bearing rock group is the important foundation of groundwater flow system analysis and groundwater numerical simulation. The accuracy and reliability of numerical simulation and flow system analysis are directly affected. In order to improve the accuracy and reliability of generalizability of water-bearing rocks, a new method of generalization of water-bearing rock groups, the cumulative water conductivity method, is proposed. The structure of water-bearing medium is generalized according to the variation of the cumulative value of the thickness of rock layer and the product of permeability coefficient with the change of depth, as well as the overall characteristics of lithology distribution in hydrogeological profile. Taking Manas River basin as an example, this method is applied to generalize the lithologic profile of the basin, and the hydrogeological structure model is constructed by using 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 three-dimensional model well shows the spatial distribution characteristics of the water-bearing medium in the study area. It lays a good foundation for the establishment of groundwater flow model.
