摘　　要：文章对焦炭塔的检验及存在的缺陷进行了分析和探讨 ,通过全面的应力分析、总应力超过材料屈服应力时的安全定性分析、无缺陷部位焊缝的热机械疲劳分析、缺陷部位的断裂评定及疲劳分析 。The inspection of the carbonization columns and flaws existed in the columns were discussed in this article. Through the stress analysis, the safety evaluation under the condition that the maximum stress was greater than the yielding stress, the thermal and mechanical fatigue analysis at the welding seam without flaw and the fatigue analysis and fracture evaluation at the location with flaws were carried out. At the same times, the measures for protecting the occurrence of the crack and handling the existence of the crack were proposed.
