地质体三维可视化是近年来铁路工程地质的发展方向。为了利用现有二维地质勘察成果直接快速地建立三维地质模型，以蒙西至华中地区运煤通道铁路裴庄隧道地质资料为基础，针对 GMS 数据特点开发地质资料自动转换程序，建立隧道周围63.54 km2范围内的三维地质模型。通过 DEM 和叠加遥感影像，真实再现裴庄隧道及周边地区的地形地貌和地层分布情况，为隧道方案比选提供了可视化手段，有助于提高地质工程师对场地复杂地质条件的认识和评价，同时对提高设计质量也具有一定的意义。

In recent years, the 3D visualization of geological body has dominated the development of railway engineering geology. In order to build three-dimensional geological model directly and quickly by using the existing 2D geological investigation results, this paper, based on the geological data of Pei Zhuang tunnel on the coal transport rail corridor from Mengxi to central China, establishes a geological data automatic conversion program based on the characteristics of GMS data. Finally a 3D geological model is established around the tunnel within the scope of 63. 54 square kilometers. With DEM and the overlay of remote sensing images, the surface conditions and stratum distributions in and around Pei Zhuang tunnel are represented, which provides a visualized method for tunnel program selection, helps the geological engineer to understand and evaluate complex geological conditions on site, and also improves the design.
