摘要
以铁路山岭隧道为研究对象,通过广泛调研提出了铁路山岭隧道BIM设计技术路线,结合＂武襄十＂铁路王家庄隧道BIM设计实践,详细论述了铁路山岭隧道BIM设计流程。实践表明,利用BIM技术构建3D模型,可以直观、准确地再现隧道与地质构造、附属结构等的空间关系,避免了常规二维设计的差错漏碰现象;通过三维可视化模型输出二维图纸及进行隧道工程数量统计保证了二维图纸相互关系的正确性及工程数量的准确性。通过应用研究初步实现了BIM与GIS系统结合,并引入FLAC3D软件对BIM隧道模型结构受力进行了三维数值模拟分析。
This thesis takes Railway Tunnel as research object,putting forward The BIM design technical route of the railway tunnel through extensive research.This paper discussed the BIM design flow of railway tunnel in detail Combined with BIM design practice of Wangjiazhuang Tunnel of ＂Wu Xiang Shi＂ Railway.The practice shows that using BIM technology to construct 3D modelcan reproduce the spatial relationship between tunnel and geological structure,subsidiary structure and so on intuitively and accurately,which avoids the mistakes often made in conventional design.Taking advantage of the three-dimensional visualization model,designer is able to output drawing and calculate construction quantity accurately.Research proves that it＇s possible to make a combination between BIM and GIS system,in addition FLAC3 Dsoftwarewas introduced to simulate the force of the BIM tunnel model structure successfully.
