提出了采用无极绳天线吊装拱肋钢管,然后利用拱肋为支撑吊装横梁的钢管混凝土拱桥吊装新方案.并结合实例证明采用此种方案吊装,可以减少吊装重量,节省吊装费用.
In this paper, new construction plan of concrete filled steel tube is put forward. And the method of lift and assemble of concrete filled steel tube arch that hang steel tube with no-end cable and hang transverse girder with strut of arch rib is described detail. And it is proved through an example that if concrete filled steel tube arch hanged with this method, the weight of hanging will be reduced, and the fee of lift and assembly will be cut down.
