重庆市支坪长江大桥工程选线设计要点分析

Analysis of Key Points in Route Selection Design of Zhiping Yangtze River Bridge Project in Chongqing

临河城市在建设过程中,必然会设计众多跨江大桥。该文以重庆市支坪长江大桥工程为例,介绍了该工程在选线过程中存在的控制因素,重点分析了铁路、现状建筑、水库、高速公路等因素在选线过程中的思考,并进行多走廊线位比选,得出了规划的中线线位最为合理的结论。并结合现场控制条件,对推荐线位的线形进行了适当调整,经济性及可建设性更为合理,为后续类似项目的建设提供参考和借鉴。

In the construction process of riverside cities, it is inevitable to design many river-crossing bridges. Taking the Yangtze River Bridge project of Zhiping in Chongqing as an example, this paper introduced the control factors existing in the process of route selection of the project, focusing on the analysis of railway, current buildings, reservoirs, expressways and other factors in the process of route selection, and made comparison and selection of multi-corridor route positions, drawing the conclusion that the planned middle route position is most reasonable. Combined with site control conditions, the alignment of the recommended route position has been adjusted appropriately, with more reasonable economy and constructability, providing reference for the construction of similar projects in the future.
