| Abstract: | Taking the Shennong Lake Bridge in Changzhi,Shanxi Province as an example,it introduces the overall design ideas&main components of a single-tower cable-stayed bridge,including pylons,pylon anchoring systems,main beams and stayed cables;the static analysis of the whole main bridge and the cable tower anchorage system is carried out.The results show that the overall structure of the main bridge meets the requirements of the specification in the completed state&construction stage,and the cable tower anchoring system is designed reasonably.The research results can provide suggestions&references for the design&calculation of similar bridges. |
