Detection Method and Application of High Speed Rail Tied Arch Bridge
According to the structural characteristics,stress characteristics,and maintenance conditions of high speed railway tied arch bridges,the testing content and methods for appearance defect detection,special inspection of suspension system,structural posture detection,material performance detection,dynamic characteristic testing,and bearing capacity calculation were specified in this paper,which were applied to the inspection of a real bridge on the Beijing-Shanghai high speed railway.The test results show that except for a small amount of external defects,the overall structural stress performance of the bridge is good,and there is no significant change compared to the initial stage of bridge construction,which verifies the effectiveness and feasibility of the detection method in this paper.
