摘要
Spar平台是目前在水深较大的深海油气田中常用的一种结构形式。Spar平台的锚固基础一般为打入式桩基或吸力锚。这两种基础形式各具特点,在设计计算上也存在着很大的差别。本文利用三维有限元对这两种基础的承载特性进行了相关研究。计算结果显示,受力角度对吸力锚和桩基的最终承栽力有明显的影响。
Spar is a kind of structure that often used in deepwater oil field nowadays. Pipe pile and suction anchor are two kinds of foundation used in Spar, and the design and analysis methods of them are very different. In this paper, we study the bearing capacity characteristics of piles and suction anchors in normally consolidated clay subject to inclined loading by three dimensional finite element. The results show that the angle of loading influences on the bearing capacity of them obviously.
