| Abstract: | Beijing Changping Nanhuan Bridge is a 175m-span steel box girder self-anchored suspension bridge. A simulation analysis of the construction process of this bridge is demonstrated. Then a method for identifying the non-stress length of the main cable from the bridge-completion state,and further determining the shape of main cable and the pre-deviation of the main cable saddle tower is put forward. A proper procedure for hanger tension is proposed,which could serve as a reference for bridge engineers. |
