摘要

大跨度拱桥采用缆索吊装斜拉扣挂施工时,索力直接关系着成桥后拱肋线形、内力和施工过程的安全.因此,确定合理的扣索索力至关重要,是施工必不可少的一项工作.文章系统的综述了目前拱桥斜拉扣挂施工扣索索力的计算研究情况,对常用的扣索索力计算方法进行详细的阐述,总结出各种方法的的优缺点.

Abstract

When a large-span arch bridge is constructed using cable hoisting and cable-stayed suspension,the cable force directly affects the arch rib shape,internal force,and safety of the construction process after completion.Therefore,determining a reasonable cable tension is crucial and an essential task in construction.The article provides a systematic overview of the curr-ent research on the calculation of cable tension in cable-stayed construction of arch bridges.It elaborates in detail on the commonly used methods for calculating cable tension and summarizes the advantages and disadvantages of each method.
