| 摘 要： | 文章针对国内少有的刚构钢箱单勒系杆拱桥,以在建的某桥为工程背景,对其施工阶段的吊杆索力进行了确定,运用影响矩阵法来确定施工阶段第二次吊杆张拉控制力,实现了仅在张拉2次吊杆的情况下,就使各吊杆索力达到成桥状态设计值,为预制拼装类施工的单勒拱桥吊杆张拉提供了实践经验.

| Abstract: | Rare in China,the steel box single-pulled arch birdge is rigidly framed.This paper with a case of a bridge construction discusses how to determine the cable force for stretching-suspending control for the second time in the construction stage by the influence matrix.To relaize that,each cable has to be up to the working state of the bridge.The paper also provides practical experience for the similar construction. |
