Abstract: Based on Guanyinyan Bridge of Jiangjin in Chongqing,the anchorage between the cable and the main beam adopts the tensile anchor plate,and most of tensile anchor plates are thick steel ones.The welding stress of welding seam among the anchor plates is eliminated and various tests are carried out after eliminating welding stress.Mathematical statistics theory and statistical analysis software SPSS are applied to judge whether the results of welding seams tests follow the normal laws;furthermore,probability credible district is adopted to judge whether the welding seams meet the relative requirements of mechanical performance.Through the study,it can deepen the understanding of physical mechanical properties of the welding connections between thick plates and ensure the safety and reliability of the welding connections of cable-stayed bridge girder and tensile anchor plate.

Key words: tensile anchor plate, detection, mathematical statistics, mechanical performance
