沈阳市公和立交桥交通分析及方案设计

沈阳市东西向交通被铁路分割,尤其是市区中部东西向交通没有联系,造成市区南部和北部地道桥交通压力过大。公和立交桥跨越电气化铁路,由于现状地形和铁路净高的要求。使主桥与东西两侧地面相对高差大,如何降低非机动车系统高程是设计的关键。此外东西两侧道路交通又相当复杂。针对这一情况论述了该立交桥交通功能需求及其解决办法。立交桥竣工后,充分发挥了它沟通铁路两侧交通的枢纽作用。

Traffic Analysis and Option Design of Gonghe Interchange Bridge in Shenyang City

The traffic in east-west directions in Shenyang City is separated by railway, especially in the middle part of the urban central district the traffic in east-west directions has not been connected so that the traffic of tunnel bridge in southern and northern parts in the urban central district has too large pressure. Gonghe Interchange spans the electrified railway. Due to the requirement of the existing terrain and the net height of railway, the difference in elevation between the main bridge and the surface on east-west two sides is relative large. How to reduce the elevation of non-motorized vehicle system is the key of design. In addition, the traffic of roads on east-west two sides is relative complex. To counter this condition the paper states the demand of traffic function and solution. After the interchange is completed it fully play a pivotal role of connecting the traffic on two sides of railway.
