摘要:
为解决自锚式悬索桥在体系转换过程中由于支座的拉拔作用而导致结构破坏与工期延长的问题,提出了一种可吸收体系转换拉拔变形的新型抗拉拔永久支座连接装置,以实现体系转换阶段主梁竖向抬升与支座受力的解耦; 该装置由水平定位机构、临时竖向位移适应机构及纵向位移适应机构组成,通过临时竖向位移适应机构提供可控位移行程,以吸收主梁抬升变形,水平定位机构用于控制合拢归位阶段的主梁水平偏差; 基于理论推导建立了支座拉拔量与拉拔力这2类拉拔效应表征指标,推导了相应的解析计算公式,并采用等代梁法和力法构建了自锚式悬索桥体系转换阶段的力学模型; 结合某独塔自锚式悬索桥工程实例,对传统吊索分级张拉法、临时压重法及提出的新方法进行了数值模拟与对比分析。研究结果表明:在吊索1次张拉至设计长度的情况下,提出的方法可实现主梁完全脱架,支座拉拔量与拉拔力均为0,主梁竖向变形完全由位移适应机构承担,有效消除了支座受力风险; 与吊索分级张拉法和临时压重法相比,提出的新方法可使体系转换工期分别缩短约61%和44%,桥下空间侵占期分别缩短约37%和27%; 新型支座连接装置能够显著提高自锚式悬索桥体系转换的安全性与施工效率,为悬索桥快速智能施工提供了新的技术路径与理论依据。
Abstract:
To solve the problem of structural damage and construction-period extension caused by the pull-out action on bearings during the system transformation process for self-anchored suspension bridges, a new anti-pull-out permanent bearing connection device capable of absorbing the pull-out deformation of system conversion was proposed to decouple the vertical lifting of main girder and bearing forces during the system transformation process. The device was composed of a horizontal positioning mechanism, a temporary vertical displacement accommodation mechanism, and a longitudinal displacement accommodation mechanism. A controllable displacement stroke was provided by means of the temporary vertical displacement accommodation mechanism to absorb the lifting deformation of main girder. The horizontal positioning mechanism was used to control the main girder's horizontal deviation during the closure and returning to position stage. Based on theoretical derivation, two pull-out effect characterization indexes, namely bearing pull-out displacement and pull-out force, were established. The corresponding analytical calculation formulas were derived, and the equivalent beam method and force method were applied to construct the mechanical model for the system transformation stage of a self-anchored suspension bridge. Combined with an engineering example of a single-tower self-anchored suspension bridge, the numerical simulation and comparative analysis were carried out on traditional hanger staged tensioning method, temporary counterweight method and the proposed new method. The research results show that when the hangers are tensioned once to the design lengths, the proposed method can realize complete de-shoring of the main girder. The bearing pull-out displacement and pull-out force are both 0, and the main girder's vertical deformation is borne entirely by the displacement accommodation mechanism. The risk of forces acting on bearings are effectively eliminated. Compared with the hanger staged tensioning method and temporary counterweight method, the proposed new method can shorten the system transformation construction period by about 61% and 44%, respectively, and shorten the occupation period of under-bridge spaces by about 37% and 27%, respectively. The new bearing connection device can significantly improve the safety and construction efficiency of the system transformation of self-anchored suspension bridges. It provides a new technical pathway and theoretical basis for the rapid and intelligent construction of suspension bridges.1 tab, 17 figs, 30 refs.
