某景观桥梁吊索设置方案的比选分析

Analysis on Comparison and Selection of Stay Cable Layout Scheme for a Landscape Bridge

现代城市桥梁的建设不仅要满足安全、适用、经济的要求,还要满足景观需求。以海南省陵水黎族自治县陵水文黎大道工程黎安互通立交主桥为背景,对此桥梁吊索设置方案的比选分析进行阐述和分析。研究不同吊索方案下桥梁的竖向位移、吊索内力、钢拱应力、主梁应力等的差异,归纳各方案的受力特性和优缺点,并提出最终方案,以期为相关工程提供借鉴和参考。

The construction of modern urban bridge will not only meet the requirements of safety,applicability and economy,but also meet the landscape demand.Taking the main bridge of Lian Interchange in Hainan Province Lingshui Li Autonomous County Lingshui Wenli Avenue Project as the background,the article sets forth and analyzes the stay cable layout scheme of this bridge,studies the differences of vertical displacements,cable inner forces,steel arch stresses and main girder stresses of the bridge by the different stay cable layout schemes,summarizes the mechanical properties,advantages and disadvantages of various schemes,and puts forward the final scheme in order to provide the reference for the similar projects.
