基于 BIM 技术的深基坑支护结构安全分析及优化设计摘 要本选题拟定在参考大量资料和 BIM 技术的基本理论和方法的基础上，本着“安全可靠、经济合理、技术可行、施工方便”原则，针对北京某岛式车站的深基坑支护结构，利用 BIM 技术中的 Revit 软件对工程原有的支护结构进行建模从而分析其安全性能，将基坑支护结构 BIM 模型与 BIM 技术中的 Navisworks 软件有机结合，对基坑支护结构进行碰撞检查，分析其现有缺陷。然后通过查阅相关支护结构法规要求，提出合理化建议，将优化设计的支护结构利用 Navisworks 软件再次进行碰撞检查，对比两次碰撞结果，看其是否达到安全等级的要求。本选题在一定程度上可以帮助做好深基坑工程支护结构的前期规划，同时还可以降低建筑事故中的人员死亡率，减少工程的经济损失。关键词：BIM 技术；深基坑支护结构；建模；碰撞检查IAbstractThe topic developed in reference a large number of information and BIM technology basic theory and method the basis, in " Security reliable, and economic reasonable, and technology possible, and construction convenient " principles, for Beijing a Island type station Deep Foundation Pit Support nursing structure, use bim technology in the revit software support nursing structure built mode to analysis of its security performance, last will Foundation Pit Support nursing structure bim model and BIM technology in the navisworks software organic combination of, to Foundation Pit Support nursing structure collision check, further contrast the actual monitoring and design workers conditions differences, verify design and construction programme rationality, see its whether reached security level requirements.This selection to a certain extent help to reduce mortality in construction accidents and reduce economic losses.Key words: BIM technology；Deep Foundation Pit Support nursing structure；bim model；clash detectionII目 录第 1 章 绪论................................................................................
