Abstract: In order to research the distribution of welding residual stress of anchorage area of tensile anchor plates,three full-scale representative models of joint in the tensile anchor plate and cable-beam of Guanyinyan Bridge are made.The results of the test show that there are different degrees of welding residual stress in main welding lines and some are close to yield strength.Through furthermore research and analysis,the characteristics,distribution rules,causes and influential factors of welding residual stress of anchorage area,as well as corresponding opinions and suggestions are put forward.The study also provides us a lot of reliable referential data for decreasing and avoiding welding residual stress in designing and manufacturing similar structural bridges.

Key words: tensile anchor plate, thick plate, welding residual stress, experimental analysis
