摘要
Abstract
Insufficient pre tightening force of high-strength bolts after final tightening,excessive vibration during bridge operation,and bolt corrosion can all cause bolt connection failure or even bolt fracture,ultimately leading to major accidents.Starting from the principle of bolt tightening,this paper proposes to use ultrasonic longitudinal wave method to detect the pre tightening force of high-strength bolts in steel bridges,and explains the principle of measuring bolt axial force using ultrasonic method.关键词
