摘要/Abstract

摘要： 本文基于GMS平台，在综合分析重庆某山区地质平面图、地质剖面图、钻孔资料等数据基础上构建了三维可视化地质模型。模拟结果表明：研究区砂泥岩倾斜互层的沉积顺序和不同岩性的空间分布情况与该区已有资料相一致；模型剖面与实际地质剖面面积之比约为1.15，主要岩性面积百分比相对误差绝对值均在15%以内。运用该模型概化为三维水文地质模型，模拟得出研究区地下水流场空间分布，体现了三维地质模型在地下水数值模拟方面的运用价值。该模型的构建为山区区域地质结构研究提供了参考，也为今后该地区开展地下水相关工作打下了基础。

Abstract: This paper aims to conduct a 3D geological model of a mountainous area in Chongqing by means of a software platform, namely, Groundwater Modelling System (GMS, after comprehensive analyzing data on geological maps, geological cross-section maps and borehole data. The simulation results showed that:sandstone-mudstone interbed of the deposition sequences and the distribution of different lithology were consistent with the existing area data; the ratio of the model profile area to the actual geological sections area was about 1.15, the absolute relative error of the main lithology area percentage were less than 15%. We built a 3D hydrogeology model based on the geological model for groundwater numerical simulation, which reflected the value of 3D geological model in the field of groundwater numerical simulation. This 3D geological model not only provides reference for geological structure of mountain region, but also lay a foundation for the future work related to groundwater research.

Key words: GMS, 3D geological model, groundwater, numerical simulation
