整幅与分幅高架设计方案研究

高架是城市快速路建设中的常用形式，根据用地、周边建筑及上位规划等控制因素，高架分为整幅与分幅形式，以济宁市西外环快速建设为背景，高架采取整幅、分幅高架形式。从交通组织、老路利用、景观效果等方面进行方案设计和对比分析，确定较为合理的快速路断面形式，为其他快速路建设提供一定参考。

Study on Design Scheme of Full-width and Sub-width Viaducts

Viaduct is a common form in the construction of urban expressway. According to the control factors such as land use, surrounding buildings, upper planning and the others, the viaduct is divided into the full-width form and the sub-width form. Taking the construction of West Outer Ring Expressway in Jining City as the background, the full-width and sub-width forms are adopted for the viaducts. The scheme design and comparative analysis are carried out from the aspects of traffic organization, old road utilization and landscape effect to determine a more reasonable section form of expressway, which provides some reference for the construction of other expressways.
