铁路工程地质BIM技术方法研究

Research on BIM Technical Method of Railway Engineering Geology

工程地质专业作为各个设计专业的基础,可为智能铁路设计提供基础地质数据。但三维地质建模技术在类似轨道交通和公路、铁路等线性工程方面尚不成熟。基于京张高铁项目,采用地层面剖切法、横向拟合拉伸方法、三棱柱法分别对地质体进行建模,并总结出了适用于铁路工程的BIM三维地质建模方法。

As the foundation of each design,engineering geology provides basic geological data for intelligent railway design.However,3 d geological modeling technology is not mature in such aspects as rail transit,highway,railway and other linear engineering.Based on the Beijing-Zhangjiakou high-speed railway project,the geological bodies are respectively modeled by using the method of strata surface cutting,transverse fitting and stretching,and the method of triangular prism.BIM three-dimensional geological modeling method suitable for railway engineering is summarized.
