摘　　要：平台结构整体实时安全评估预警值的确定对掌握海洋平台结构整体安全状况来说十分重要。该文基于结构设计规范对结构的安全状况进行了划分,并建立了结构实时安全评估的两级预警值。结合海洋平台整体结构的特点,建立了结构实时安全评估两级预警值的确定原理和方法,并将该方法应用于JZ20-2MUQ平台,获得了结构二级预警值,可作为实际工程应用参考。In order to reasonably know the real-time safety situation of in-service offshore platform structure, the warning indexes for real-time safety assessment of in-service offshore platform structure is very important. Based on the classification of the structural safety situa- tion in the structure design code, the warning value for real-time safety assessment of in-serv- ice offshore platform structure is classified as two levels. According to the overall mechanics property of the offshore platform structure, the calculation method of the two level warning indexes is presented. It is applied to the platform structure of JZ20-2MUQ platform, the actu- al warning indexes are determined. This can be a reference for the determination of structural safety situation in the engineering application of structural health monitoring （SHM）.
