摘　　要：为解决传统铁路电子沙盘建设过程中设计模型建模慢、模型系统融合性差等问题,以AnyCAD库为基础,通过读取桥梁算单中的部件参数,进行桥梁算单建模、转换、集成方法研究,并以隧道构件库为基础,通过隧道装配表统计,进行隧道装配式建模和集成方法探索,以明确电子沙盘三维场景构建、三维中线制作的方法与要求。通过实验统计,相较于传统参数化建模,桥梁算单建模效率提高78.7倍,隧道装配式建模效率提高14.7倍,实现了桥梁、隧道设计模型的快速建模。In order to solve the problems of slow modeling of design model,poor integration of modeling system in the construction of traditional railway electronic sand table,based on AnyCAD library,this paper studied the methods of modeling,conversion and integration of bridge form by reading the component parameters in bridge form,and studied the method of modeling and integration of tunnel assembly based on tunnel component library and statistics of tunnel assembly table.Besides,the methods and requirements of three-dimensional scene construction and three-dimensional midline production of electronic sand table were discussed.Through experimental statistics,compared with traditional parametric modeling,the efficiency of bridge calculation modeling is improved by78.7 times,and the efficiency of tunnel assembly modeling is improved by nearly 14.7 times,which realizes the rapid modeling of bridge and tunnel design models.
