Abstract: Many municipal pipeline engineering need to occupy the busy urban main road in construction period，which make the essential bad urban traffic one disaster after another．This paper roundly dissertate the design out-line and technique of traffic organization in construction period，introduce the method of checking computations about road capacity and saturation in detail，analyzing how to lay traffic establishment and how to arrange working procedure in reason, which will make the impact roduce to the least．Finally，illustrate the Huang Pu district trunk sewer network’traffic organization in construction period，using the qualitative and quantitative methods to set down feasible project，it is significant for engineering practice．

Key words: municipal pipeline engineering, construction period, traffic organization

摘要： 许多城市管道工程施工期间需要占用交通繁忙的主要千道，给本来就难于负重的城市交通雪上加霜。针对该问题，本文系统地研究了管道施工期间交通组织的设计要点和设计方法，详细介绍了验算道路系统容量和饱和度的方法，重点分析了在施工期间如何合理布置交通安全设施以及如何科学安排工期工序，以使得施工围蔽对周边道路交通的影响降至最低。论文最后以广州市黄埔区污水干管工程施工期间交通组织设计为例，采用定性和定量相结合的方法制定科学可行的方案，研究成果对工程实践有一定的指导意义。
