筒型基础总体尺寸初步设计方法

筒型基础平台是一种新型海洋平台，它通过在筒腔内产生一个比周围小的压强而自主插入海底，工作期间又具有在筒腔内形成负压来增强抵抗外载荷的能力。本文介绍一种以抗拔能力为设计基准的筒型基础总体尺寸的初步设计6方法，并对方法中的各参数提出了选用原则和取值范围，给出了相应的计算图谱，最后还以两个筒型基础为例演示了方法的使用。

Initial design method for bucket foundation′s general dimensions

The bucket foundation platform(BFP) is an up to date ocean plarform in the world. It can insert itself into the seabed by producing less pressure in its cavity than that of the circumambience. It can also produce suction in the cavity to increase its ability to endure the force coming from environment. In this paper, a method of assessing the value of bucket foundations by predicting foundation capacity from soil properties, foundation geometry, and suction intensity is presented. Design graphs and charts are presented to simplify the bucket foundation design, and typical design examples are given to demonstrate the use of this method.
