摘　　要：为合理研究风浪载荷作用下导管架平台的承载能力,基于静力推覆分析提出风级增量分析方法。以两种不同类型的导管架平台为例,利用风级增量分析和静力推覆分析对平台的承载能力进行评估,划分不同风级下的平台状态,并对平台进行安全分级。结果表明,平台的安全状态可通过风级当量表示,与静力推覆分析相比,风级增量分析能够正确地反映不同环境下导管架平台的承载能力。本研究可为导管架平台在风浪环境下的安全评估提供参考。In order to study the bearing capacity of jacket platform under wind and wave loads,the method of wind scale incremental analysis is proposed on the basis of the static pushover analysis.Wind scale incremental analysis and static pushover analysis are used for wind resistance capacity assessment of two different types of jacket platform.By dividing the status of platform under different wind scales,the bearing capacity and safety classification of the platform are obtained.The results show that wind scale equivalent can represent the safety status of jacket platform.Compared with the static pushover analysis,wind scale incremental analysis can reflect the bearing capacity of jacket platform accurately in different environments.The research provides a reference for safety assessment of the fixed platform in wind and wave environments.
