| 摘 要： | 地下水数值模拟软件GMS提供了基于钻孔资料的三维地层生成模块,借助于GMS软件中地层模拟模块,利用钻孔数据、地层剖面资料、地质图和DEM数据,结合虚拟钻孔方法,构建了复杂地质结构区—北京顺平地区三维地层结构模型,模型包括太古宇密云群,长城系、蓟县系、青白口系、寒武系、奥陶系、石炭—二叠—侏罗系、深层第四系和浅层第四系等9组地层,刻画出了各层分布的空间范围,模拟了山区地表高程的起伏变化、断层产生的地层错动等情况,为研究区地质和水文地质条件分析及地下水数值模型的建立奠定了基础。

| Abstract: | GMS-groundwater numerical modeling software may supply solid module, which is used to construct three-dimensional models of stratigraphy. Based on borehole data, geological cross sections, geological map and DEM data, combined with the virtual borehole, the three-dimensional models of stratigraphy of Shunyi-Pinggu Districts in Beijing was established, which includes nine stratigraphic units—Archean Miyun Group, Changcheng System, Jixian System, Qingbaikou System, Cambrian System, Ordovician System, Carboniferous - Permian - Jurassic System,Quaternary System(shallow and deep) . The model described spatial scale of each stratigraphic unit and simulated topographic relief in mountain area, strata faulting etc. The model provide basis for groundwater numerical modeling. |
