Self-anchored suspension bridge sling non-lengthening system conversion method
The invention relates to a self-anchored suspension bridge sling non-lengthening system conversion method. The method comprises the following steps that (1) partial second-phase dead load construction is synchronously carried out in an erection stage of a reference strand; (2) first-round tensioning of the slings is carried out, specifically (2.1) a first group of slings, a second group of slings and other groups of slings corresponding to a main span long section are firstly tensioned according to a sequence of first short slings and second long slings; (2.2) each group of slings corresponding to a non-main-span long section is symmetrically tensioned according to the sequence of short cables and long cables; (3) residual second-stage dead load construction is carried out; and (4) the slings are tensioned for the second round, specifically, all the slings are symmetrically tensioned from the two sides of the bridge tower one by one according to the sequence of long slings first and then short slings till the structure is in a reasonable bridge forming state; the step (3) and the step (4) are adjustable in sequence but cannot be carried out crosswise. The method is advantaged in that construction efficiency is improved, measure cost in construction is saved, and the formulating process of a system conversion scheme is simplified.
本发明涉及一种自锚式悬索桥吊索不接长体系转换方法，包括以下步骤：(1)、在基准索股的架设阶段同步进行部分二期恒载的施工；(2)、吊索第1轮张拉，其包括：(2.1)按照先短索后长索的顺序首先张拉主跨长出段对应的第1组吊索、第2组吊索和其它组吊索；(2.2)、按照先短索后长索的顺序对称张拉非主跨长出段对应的各组吊索；(3)、进行剩余二期恒载的施工；(4)、吊索第2轮张拉，按照先长索后短索的顺序从桥塔两侧逐对对称张拉各组吊索，直到结构合理成桥状态。其中，步骤(3)和步骤(4)顺序可调但是不可交叉进行。其提高了施工的效率、节省了施工中的措施费用、简化了体系转换方案的制定过程。
