Structural geological 3D model for the Erzgebirge railway tunnel

Structural geological 3D model of the area of interest was created in the MOVE software, which is suitable for the modelling of complex geological environment of the Bohemian massif crystalline and enables simple import and export of various data formats. The aim of the model is the unified visualisation of the geology and faults below the surface in correlation with the planned routes of the railway. The majority of the modelled area is located in the crystalline rocks of the Erzgebirge mountains which belong to the Saxothuringian Unit. The modelled area is separated into a Czech and German part, both were modelled separately and merged at the end. The extent of the German part of the 3D structural geological model is an extension of the former 3D model of 2015 (Goerz in Buske et al. 2015). The current extent is based on different alternative routes of the planned high-speed railway as defined by the Czech and German Railway administrator organisations.本研究针对目标区域构建了三维构造地质模型，建模工作基于MOVE软件开展。该软件适配波西米亚地块结晶岩区的复杂地质环境建模需求，支持多种数据格式的便捷导入与导出。本模型的构建目标为，结合拟建铁路线路，统一可视化展示地下地质体与断层分布。建模区域主体位于隶属于萨克森-图林根构造单元的厄尔士山脉结晶岩分布区。该建模区域划分为捷克段与德国段，两段分别完成建模后再进行最终拼接整合。本三维构造地质模型德国段的覆盖范围，是对2015年原有三维模型的延伸（该2015年模型相关内容见于Buske等2015年的研究成果，相关工作由Goerz完成）。当前模型的覆盖范围，依据捷克与德国两国铁路管理机构划定的多条拟建高速铁路备选线路确定。
