摘要
运用索力优化的理论方法,计算确定梁拱组合桥吊杆合理的成桥索力和施工索力,并分析其对结构应力和位移的影响,为同类型桥梁结构的索力优化设计和施工索力调整提供思路和参考依据。
This paper uses the theoretical method of cable force optimization to calculate and determine the reasonable bridge cable force and construction cable force of girder and arch composite bridge hanger.It analyzes the influence on structural stress and displacement and provides ideas and references for cable force optimization design and cable force adjustment in construction of the same type of bridge structures.
