摘要
破碎波冲击载荷是极浅水固定式风机基础设计中不可忽略的载荷,但工程实践中对其评估方法并不成熟。本文介绍了海上固定式单桩风机基础在破碎波作用下的准静力和时域冲击力的计算原理和方法,以实际案例为基础,对于不同规范方法计算的破碎波冲击力进行了对比,采用SACS软件进行破碎波冲击载荷下的动态响应分析,给出了若干结论和建议,可为同类型项目的结构设计提供借鉴。
Breaking wave loads have significant impact on offshore monopile WTG foundation,and there is no mature engineering practice to evaluate its impact on the structure appropriately.This paper summarize different evaluation methods on static and time-history impact loads from breaking waves,and a typical monopile WTG foundation is presented to analyze the breaking wave impact and overall dynamic response,several conclusions and reasonable suggestions are presented for monopile WTG foundation design and analysis.The proposed method and suggestion in this paper can provide reference for other similar project.
