与轨道交通同位并行、站桥分离合建的城市立交桥总体设计

Overall Design of Urban Interchanges Built in Parallel with Rail Transit and Separated from Stations&Bridges

依托太原市尖草坪立交桥改建工程,介绍了与轨道交通L2西涧河站前站后区间段同位并行、站桥分离合建的尖草坪立交桥改建工程的总体设计和关键构造设计。通过对与轨道交通同位并行、站桥分离合建、先立交后轨道交通、一期立交保通的城市“Y形”部分互通立交工程设计要点进行归纳总结,可为今后类似工程设计提供借鉴。

Based on the reconstruction project of Jiancaoping Interchange in Taiyuan,it introduces the overall design&key structural design of the Jiancaoping Interchange reconstruction project,which is built in parallel with the front and rear sections of Xijianhe Station in rail transit L2 and separated from the station&bridge.By summarizing&summarizing the design points of urban Y-shaped interchanges that are parallel to rail transit,separated&constructed from stations&bridges,followed by overpasses&rail transit,and the first phase of interchanges,which can provide reference for similar engineering designs in the future.
