Abstract：Research purposes: Based on the three - dimensional modeling and visualization technology，railway BIM - based design implements virtual construction of the subgrades， bridges， tunnels， stations and buildings. Three - dimensional geological modeling is a kind of technology，which supports the interaction between geological experts and computer software and hardware， deducing the geological conditions of a piece of three - dimensional space， forming three - dimensional geological model， and visualizing the model in computer. In this paper， three - dimensional simulation of railway engineering geological conditions is achieved based on the three - dimensional geological modeling technology，which can provide three - dimensional geological information services for the railway BIM - based design. Research conclusions ：( 1) Three - dimensional simulation of railway engineering geological conditions is of specialty， so the traditional three - dimensional geological modeling technology in the mineral and energy fields is not suitable. The three - dimensional geological modeling technology with the linear borehole in this paper achieves the three - dimensional simulation of engineering geological conditionsin railway bridge section effectively. ( 3 ) The research results can provide the three - dimensional geological information for railway BIM - based design.
