中承式钢管混凝土系杆拱桥设计

Design of Half-Through Tied-Arch Bridge with Concrete Filled Steel Rib

以上海蕰藻浜大桥设计为基础,从钢管拱肋应力控制、伸缩缝位置的选取、边拱线型设计以及拱座局部应力分析等,对中等跨径钢管混凝土拱桥的建设做诸多优化设计研究的尝试和实践。经过施工过程和最近几年对该桥的监控检测,结果表明该桥几个主要的创新设计具有良好的实际效果。

With the background of Shanghai Wenzaobang Bridge design,from the aspects of stress control of steel arch rib,selection of expansion joint location,side arch design and local stress analysis of arch abutment,many at tempts are made to optimize the design of medium-span CFST arch bridge.After the construction process and monitoring of the bridge in recent years,the results show that the bridge of several major innovative design has good practical results.
