The invention discloses a connection structure, a fixing structure, a new main cable system and a construction method for replacing the main cable of a suspension bridge. Disadvantages of replacement.

Description

technical field [0001] The invention relates to a main cable connection structure of a suspension bridge, in particular to a connection structure, a fixing structure, a new main cable system and a construction method for replacing a main cable of a suspension bridge. Background technique [0002] At present, the main cable structure of many suspension bridges has rust, corrosion, broken wires and other diseases. With the increase of service life, the diseases of suspension bridges will appear one after another. The main cable is the lifeline of the suspension bridge and the most important stress member in the suspension bridge, bearing all the static and dynamic loads of the entire bridge superstructure. In order to ensure the safety of the bridge, technical research on replacing the main cable is imminent. At present, the replacement of the main cable needs to stop traffic and replace parts one by one. During the whole replacement process, there is a high risk of deformati...
