| 摘 要： | 上承式系杆连拱拱桥是一种新兴的系杆平衡水平推力的拱式结构,国内工程已有先例.其主要特点是系杆在所有拱轴线的上方施加水平预应力,将连拱传递给曲杆梁的水平推力抵消,最终形成对两端基础无水平推力的自平衡式结构.文中介绍了一座新设计完成的上承式系杆拱桥,给出了地基的模拟方式、体外索和主拱肋的应力情况.提供的计算结果表明其结构形式的合理性.

| Abstract: | Top road multi-span arch bridge,which uses externally prestressing cables to balance the horizontal pushing force,is a new type of arch bridge developed in recent years.Until today,there are not widely built national-wide.The typical character of this kind of arch bridge is that,the cables are prestressed above all the arch ribs to balance the horizontal force transferred to the curve girder,which finally makes up the self-balanced structure with no horizontal pushing force to the end foundation.A newly-des... |
