无横梁桥面系梁拱组合桥梁施工控制研究

Research on the Construction Control of Girder and Arch Combination Bridge with Non-horizontal Beam Deck

大连新建北岗桥为无横梁桥面系梁拱组合桥梁,针对其施工过程受力特点,采用平面杆系有限元模型并优化张拉顺序模拟施工过程,从理论上预测出每个施工阶段的内力及变形。

Newly-built Beigang Bridge in Dalian is a girder and arch combination bridge with non-horizontal beam deck. According to its load features in construction process,this paper simulates the construction process with planar bar system＇s finite element model and optimizing tension sequence,and forecasts theoretically the internal forces and deformations in each construction stage.
