| 摘 要： | 广东东莞东江大桥是一座刚性悬索加劲三桁双层桥面钢桁梁桥，结构新颖，受力性能复杂，合龙口合龙点多，合龙难度大。，以此工程为依托，分析自重及吊机荷栽对钢桁梁合龙的影响，结果表明：自重引起的变形对铜桁梁合龙的影响比较显著,吊机荷载对铜桁梁合龙的影响很小。

| Abstract: | Dongjiang Bridge in Dongguan City of Guangdong Province is double-deck and three main trusses steel bridge with rigid cable. Its structure is novel and force property is complex. What＇s more, there are more closure points and the closure is difficult. Combining with this project, the in- fluence of dead weight and crane load on steel bridge is analyzed. The results show that the influence of dead weight is obvious, while the influence of crane load is less relatively. |
