广佛共建示范先导区首条交通性过江通道多方案综合比选

Comprehensive Comparison and Selection of Multiple Schemes for a Traffic River-crossing Channel Firstly in Guangzhou - Foshan Co-construction Demonstration Pilot Area

摘要:

针对广佛共建示范先导区首条交通性过江通道的总体选线和过江工法进行了多方案同深度比选。在对过江通道工程关键控制因素进行分析的基础上，对A线、B线、C线、K线4条线位进行了比选；从是否符合城市规划发展、是否影响自然环境、是否符合沿线居民利益等方面对桥梁和隧道两个过江方案进行了比选；从控制因素、平纵布置等方面对隧道施工沉管工法和盾构工法进行了比选。经过多方案比选，最终确定了兼顾多方利益、切实可行的推荐方案。

Abstract:

Aiming at the general route selection and the river-crossing method of the first traffic river-crossing channel of Guangzhou - Foshan Co-construction Demonstration Pilot Area, many schemes are further compared and selected. On the basis of analyzing the key control factors of the river-crossing channel project, four alignments of Line A, Line B, Line C and Line K are compared. Two river-crossing schemes of bridge and tunnel are compared and selected from whether or not to meet the urban planning development, to affect the natural environment, to satisfy the benefits of the residents along the line. The sinking pipe method and shield method of tunnel construction are compared from the control factors, and the horizontal and longitudinal layouts. After the multiple scheme comparison, finally, a feasibly recommended scheme is determined in consideration of the benefits of all.
