地铁施工期间临时迁改道路设计研究

摘要

地铁施工期间会不同程度地占用城市道路,影响道路的通行,对居民的出行造成干扰.通过对地铁沿线片区路网进行交通疏解,可以有效地降低地铁施工期间对城市交通的影响,保证片区居民的正常出行.临时迁改道路的快速实施为地铁施工及交通疏解提供了有力的支撑.同时临时迁改道路的线形指标又直接影响到通行的安全及工程的造价,对交通疏解至关重要.%The construction period of metro will inordinately occupy the urban roads, affect the road traffic and cause the disturbance to the travel of the residents. The traffic reconciliation of regional road network along the metro can effectively reduce the influence of metro construction period on the city traffic, and guarantee the normal travel of regional residents. The fast implementation of temporary relocation road provides the powerful support for the metro construction and traffic reconciliation. At the same time, the alignment index of temporary relocation road will directly impact the traffic safety and engineering cost, which is very important to traffic reconciliation.
