四桩腿海洋平台支反力计算研究

Calculation Study of Counterforce for Four Leg Offshore Platform

对于四桩腿自升式海洋平台,其桩腿支反力计算属于超静定问题。常规计算方法形式繁琐,过程复杂。论文采用一种新的计算方法,能够快速得到在任意重量重心分布下的各桩腿支反力计算结果,并利用某375ft自升式生活辅助平台对这一结论进行验证。论文的研究工作为工程实际提供快速、便捷的计算依据,具有工程实际意义。

For four leg offshore platform,the solution of support reaction belongs to indeterminate.Traditional methods for calculation and process are complicated.In this paper,a new calculation method is used,which can quickly get results of each leg support reaction force in the center of gravity of any weight distribution,and a 375ft Self-elevating Life Boat is used to validate this conclusion.The research work of this article provides fast and convenient basis for the actual project and calculation,which has practical significance in engineering.
