摘　　要：以K5-MOPU自升式平台风暴自存状态桩腿强度为研究对象,采用规范公式法和有限元法相结合的方法,分别计算平台承受的风、浪、流等环境载荷,以及由波浪载荷引发的动态放大因子,并考虑平台侧向位移引发的P-Δ效应载荷。根据规范要求分别校核平台桩腿强度,分析平台地基承载能力和预压载能力,并计算分析桩腿锁紧装置的承载能力和平台抗倾稳性。结果表明平台结构强度满足设计要求。Taking the K5-MOPU jack-up platform's self-existing state pile leg strength as the research object,using a combination of the normative formula method and the finite element method,the environmental loads such as wind,waves,and currents on the platform are calculated separately,as well as those caused by wave loads.The dynamic amplification factor of,and consider the P-Δeffect load caused by the lateral displacement of the platform.According to the requirements of the specification,the strength of the platform legs is checked separately,the platform foundation bearing capacity and preload capacity are analyzed,and the bearing capacity of the leg locking device and the platform anti-tilting stability are calculated and analyzed.The results show that the structural strength of the platform meets the design requirements.
