Method for monitoring health state of corrugated steel web bridge

The invention discloses a method for monitoring the health state of a corrugated steel web bridge. The method comprises the following steps of: additionally arranging a plurality of static strain measuring points and dynamic strain measuring points on sections near adjacent mid-span fulcrums; a plurality of dynamic strain measuring points are additionally arranged on the cross section of one fourth length of the midspan; collecting real-time data of each static strain measuring point and each dynamic strain measuring point through a monitoring system for evaluation and early warning; according to the invention, on the basis of guaranteeing the monitoring of the stress and operation safety of the whole structure of the corrugated steel web bridge, a plurality of static strain measuring points and dynamic strain measuring points are additionally arranged on the sections near adjacent mid-span fulcrums according to the characteristics of the corrugated steel web bridge; and meanwhile, a plurality of dynamic stra
