摘　　要：通过在小湾立交工程上开展的BIM技术应用,详细梳理了整个复杂市政立交BIM模型建立的思路及正确流程,研究了基于BIM技术的土方调整、碰撞检测、视距检查和净空检查等技术应用,尝试了BIM出图和VR展示。研究表明:在市政立交设计中运用BIM技术,可有效的优化立交平面线形、纵断面、构造物结构及位置;利用BIM模型进行工程量统计复核及三维出图,可提高设计文件质量,在表达设计意图方面也更加直观。Through the application of BIM technology in the Xiaowan Interchange project,the idea and correct process of the establishment of the whole complex municipal interchange BIM model was combed in detail.And then the technology application of earthwork adjustment,collision detection,visual distance inspection and headroom inspection based on BIM technology were studied.Finally,BIM mapping and VR display were tried.The research shows that the application of BIM technology in the design of municipal interchange can effectively optimize the linear shape,longitudinal section,structure and position of the intersection;and the use of BIM model to carry out statistical review of engineering quantities and three-dimensional mapping can improve the quality of design documents and express the design intention more intuitively.
