Embodiment 1
[0041] A method for quickly identifying the state of a main cable of a suspension bridge, comprising the following steps:
[0042] First, after starting the monitoring computer, start monitoring the alignment of the main cable and the bridge deck, and determine the displacement v of the upper and lower ends of each sling i , Simultaneously measure the tension N of each sling i , according to the formula (1) to calculate the vertical restraint stiffness k of a single sling to the main cable i , according to the formula (2) to calculate the vertical restraint stiffness k of the sling to the main cable per unit length
[0043] k i = N i | v i - v i ′ | - - - ( 1 ) ...
