| Abstract: | Based on the project of a new television tower in Guangzhou,the blind-hole method is employed in this paper to measure the longitudinal and circular residual stress in the inner and outer surface of a steel tube.Test results indicate that the method can be used to measure the distribution and the value of the residual stress,which provides a scientific reference for structural engineers. |

| Keywords: | thick plate steel tube with large diameter and straight-line welding inspection of residual stress blind-hole method strain release coefficient |
