摘　　要：梁拱组合桥梁为内部超静定结构,针对其施工过程受力特点,通过影响矩阵法优化吊杆张拉顺序模拟施工过程,预测出每个施工阶段的内力及变形,为吊杆张拉施工控制提供理论指导依据。Beam arch combined bridge is an internal statically indeterminate structure. In view of its construction process stress characteristics, the internal force and deformation of every construction stage are predicted through the influence matrix method optimizing steeve tension sequence and simulating the construction process, which may provide theoretical guidance for sling tension construction control.

关 键 词：影响矩阵法张拉顺序 梁拱组合桥梁 内力影响
