基于 BIM 技术对市政地下管网的优化设计摘 要为提高城市污水管网的收水能力，目前国家正致力于改造传统雨污混合流为雨污分流制并实现城市化，在实施过程中由于原污水管道的结构复杂及质量低下，在改造过程中极易因路面开挖、管线布置失误等导致管道堵塞而造成二次甚至多次开挖，影响工程进度。BIM 技术应用主要集中在建筑设计领域，通过对工程的 3D 建模，建造出三维的信息化模型，使市政管网建设或改造的设计表达更立体直观，工程量统计更准确，并可以对模型进行施工模拟及工程全生命周期管理，直接反应出该工程设计上出现的问题然后做出改进，提高工程质量。关键词：地下管网；BIM北京理工大学珠海学院 2020 届本科生毕业论文AbstractIn order to develop the capacity of the water collection pipe network which is missing in the city, the traditional mixed water system has now been transformed into water water water and urbanization system. Due to the reasons of water quality, tension, wrong water, etc., the original water pipes are undergoing water quality transformation. There may be more or more excuses to influence the development of the project. BIM Technology is usually used in architectural design. This project establishes a three-dimensional information model. When designing or changing the urban network, it can give a visual display and more accurate statistical data development of process sections.Keywords: Underground pipe network；BIM北京理工大学珠海学院 2020 届本科生毕业论文目 录第一章 引言........................................................................................................6第二章 雨污分流..................................................................................................82.1 雨污分流介绍..........................................................................................82.2 雨污分流（分流制）的主要优势..................................................................82.3 雨污分流管网在建设中存在的缺陷..............................................
