对海洋石油平台T型管节点损伤进行了声发射监测，并对损伤检测过程的声发射信号进行K 均值聚类分析，以声发射参量的相关性为依据选取损伤特征参数，实现了对T型管节点不同损伤阶段信号的有效识别，为T型管节点的损伤监测和不同损伤阶段的模式识别提供了依据。
對海洋石油平檯T型管節點損傷進行瞭聲髮射鑑測，併對損傷檢測過程的聲髮射信號進行K 均值聚類分析，以聲髮射參量的相關性為依據選取損傷特徵參數，實現瞭對T型管節點不同損傷階段信號的有效識彆，為T型管節點的損傷鑑測和不同損傷階段的模式識彆提供瞭依據。

An experiment was performed on the offshore platform T-tube node for the purpose of understanding its damage mechanism.Characteristics of acoustic emission signal of the offshore platform T-tube node at different damage stages were obtained by using the K-means clustering analysis.The damage characteristic parameters of the acoustic emission signal were first selected based on the correlation analysis.The proposed method could thus effectively realize the recognition of T-type pipe node at different damage stages.The study should provide reference for damage monitoring of T-type pipe node and the identification of its different damage stages.
