一座海洋平台改造的强度分析

The Strength Analysis of the Reformation of an Offshore Platform

对一座海洋平台改造前和改造后各种工况进行了结构强度计算,对摩擦桩与平台主体之间的不同连接方式进行比较,分析了考虑风冰载荷下发生桩靴滑移时桩腿的应力变化情况。为该平台的改造与工作状态下的强度安全评估提供了重要的参考。

A four leg jackup platform is reconstructed to be a fixed sixleg platform by adding two friction piles.The strength of the platform before and after reconstruction at different working conditions are calculated.Different connection modes between the friction piles and the main part of the platform are compared and the effects of the pile shoe sliding under the wind and ice loading are analyzed.
