| Abstract: | The manufacture process for the steel tube on main arch is the difficult point for constructing the extra long arch bridge of steel tube over Jinghang Canal on Lianxu Expressway. During construction, the process of tube bent by fire was adopted, which was different from the conventional method. As a matter of fact, it brings the obviously economical result and makes itself a good example for the following engineering. |
