城市快速路的选线优化设计分析

Analysis on the Optimization Design of Route Selection for Urban Expressways

文章以城市快速路选线设计为切入点,结合西环快速路与铁路交叉工程实例,明确了快速路选线设计原则,并结合选线设计阶段存在的主要问题提出城市快速路选线设计优化策略,包括全面布局、具体定线、问题处理、量化评价和方案比选,旨在建立更完善的选线设计体系,突破传统选线设计模式局限性,提高选线设计的科学性及可行性,为同类型工程选线设计工作开展提供参考。

Taking route selection design of urban expressway as the breakthrough point,combined with West Ring Expressway and railway intersection engineering example,this paper clarifies the design principle of expressway route selection,and puts forward optimization strategies for urban expressway route selection design based on the main problems existing in the design stage of route selection,including the comprehensive layout,specific alignment,problem handling,quantitative evaluation and scheme comparison.The purpose is to establish a more perfect route selection design system,break through the limitations of traditional route selection design mode,improve the scientificity and feasibility of route selection design,and provide reference for the route selection design of the same type of engineering.
