摘要
新密市溱水路大桥主桥采用新型的钢-混组合结构梁独塔无背索斜拉桥桥型,主梁主塔为波形钢腹板混凝土箱梁。主桥为墩塔梁固结体系,塔身倾斜,斜塔倾角59°,主塔施工难度非常大,质量控制困难。依据设计特点,对斜塔施工进行了合理的节段划分,为克服斜塔实心混凝土结构施工困难,对施工方案进行详细的比选和研究,并对方案实施进行了详细阐述。
The original structural single tower cable stayed bridge without back stays is used in the main bridge on Zhens-hui Road in Xinmi City.The main girder is box girder with corrugated steel webs.Pier,tower and girder of the main bridge are consolidated together.The dip angle of the main tower is 59 degrees.Construction of the main girder is very difficult. Based on the design,segmental division is made of the main tower construction.To overcome the difficulties of construc-tion,comparison and study were made on the construction scheme which was explained in details.
