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。 Aiming at the rare steel frame single-lever tied arch bridge in China, taking a certain bridge under construction as the engineering background, the cable force of the boom in the construction stage was determined. The influence matrix method was used to determine the second Suspension tension control force, to achieve only in the case of tension 2 times the boom, the boom force to make the bridge into the state of the design value for the prefabricated construction class single Lele arch bridge boom provided Experience.
