摘　　要：对铁路地质三维建模方法进行总结,并探讨铁路地质三维建模思路。论述Bentley平台下的地质建模方法:将工程区域内的环境和钻孔数据录入Bentley数据端,在Bentley图形端制作岩性分界面,然后对规则块体进行切割,得到有体积的网格或者智能实体;最后给地质属性赋值,得到铁路三维地质体模型成品。研究表明,基于Bentley平台的地质体模型成品可以很直观地表达岩层在三维空间下的分布状态,经过属性赋值后,可以轻松地查询到岩层参数,弥补了传统二维设计在铁路设计中的缺点和不足。This paper summarizes the 3-D geological modeling method of railway, and discusses the 3-D geological modeling thought of railway. The geological modeling method under Bentley platform is expounded: Input environmental and borehole data into Bentley data terminal, make lithologic interface at Bentley graphics terminal, then cut regular blocks to get grids or intelligent entities with volume, finally assign geological attributes to every grid or intelligent entity. At this time we finish the railway 3-D geological model. Research shows that the model based on Bentley platform can directly express the distribution of rock strata in three- dimensional space. Rock parameters can be easily queried through assigning geological attributes. That makes up for the shortcomings of traditional two-dimensional railway design.
