Theresultsshowthatapplyingtheestablishedbridgeremaininglifepredictionmodel totheexamplecanpredict theremaining life of the bridge，andtheresultsareconsistentwiththeactual situation，indicating thattheestablishedbridgeremaining life prediction model is feasible and provides a new research method for predicting the remaining life of the bridge.
