摘要
文章以某自升式平台穿刺事故后的维修为例,通过利用有限元数值模拟辅助分析桩腿受损后变形的内应力,损坏舷管割除后的桩腿的稳性,指导现场制定精确的桩腿修复方案,并通过施工验证,为以后自升式平台桩腿的类似维修提供借鉴参考。
Taking the maintenance of a jack-up platform after a puncture accident as an example,by using finite element numerical simulation to analyze the internal stress of the pile leg after the damage,the stability of the pile leg after the cut off of the side pipe is damaged,and the accurate repairing scheme of the pile leg is directed to be worked out on the spot. And through the construction verification,for the future self-lifting platform pile leg similar maintenance to provide reference.
