摘　　要：市政工程具有周期长、涉及范围广、施工量大,对周边影响大等特点,为缓解交通压力,首先对交叉口通行能力进行分析,运用高峰小时系数PHF来判断各路段交通拥堵状况。再提出一整套交通疏导方法,从交通疏导线的设计原则、设计步骤进行研究。西安市幸福林带项目是全球最大的地下综合空间,本文依托西安市幸福林带项目进行交通疏导方法设计,提出创新型先导后行交通疏导方法,有效的降低了在施工过程中对周围交通的影响,为国内外其他城市超长线性地下工程施工时期的道路交通疏解方案提供了参考价值。Municipal engineering has the characteristics of long cycle,wide coverage,large construction volume and great influence on the surrounding area.Therefore,in order to alleviate the traffic pressure,the traffic capacity of the intersection is analyzed first,and the peak hour coefficient PHF is used to judge the traffic congestion of each road section.Then a set of traffic grooming methods is proposed,which is studied from the design principles and design steps of traffic lines.The Xi'an Happiness Forest Belt Project is the largest underground comprehensive space in the world.This paper relies on the Xi'an Happiness Forest Belt Project to design the traffic guidance method,and proposes an innovative pilot-led traffic guidance method,which effectively reduces the impact on surrounding traffic during the construction process.It provides reference value for road traffic dispersal schemes during the construction of ultra-long linear underground engineering in other cities at home and abroad.
