摘要
广州城市快捷路二期是广州中心城区内外环之间的辅助环形连续交通道路,同时也是白鹅潭地区"三环七射"道路骨架系统的三环之一,过江通道两岸具有接线路网复杂、沿线城中村及建设地块密集等特点,总体设计难度大.详述了过江通道建设的意义,综合考虑总体规划、城中村改造计划、征地拆迁、环境效应和江中通航要求等因素,先进行线位比选,然后进行过江桥隧方案比选,最后通过隧道工法比选,对过江通道总体设计做了细致的分析比对,最终选取了过江沉管隧道作为实施方案.该项目对缓解城市交通压力和加速项目沿线经济快速发展具有重要意义,同时也为沉管隧道建设进一步积累经验.
Abstract
The Guangzhou Urban Expressway Phase Ⅱ is an auxiliary ring continuous traffic road between the inner and outer rings of the central city of Guangzhou,and is one of the three rings of the"three rings and seven shots"road skeleton system in the Baietan area.There are characteristics of complex connecting line road network,village in city along the line and dense construction plots at both sides of the cross-river passageway.The overall design is greatly difficult The significance of the cross-river passageway construction is described in detail.By comprehensively considering the factors of overall planning,village-in-city reconstruction plan,land acquisition and demolition,environmental effects and navigation requirements in the river,firstly the line positions are compared,then the schemes of the bridge and tunnel across the river are compared,and finally the overall design of the cross-river passageway is analyzed and compared in detail through the comparison of tunnel construction methods.At last,the immersed tunnel is selected as the implementation scheme.The project is of great significance to alleviate the pressure of urban traffic and accelerate the rapid economic development along the project,and also to further accumulate experience for the construction of immersed tunnels.
