摘要
深卧基础式采油平台采用—种由沉箱及底粱构成的组合式基础,同传统的导管架式平台相比,具有工程上,经济上明显的特色,但其基础与土相互作用的力学机制尚待深入研究。本文介绍深卧式基础与土在垂直及水平荷载作用下的三维非线性有限元分析,以及配合开展的模型实验。计算与实验的结果基本吻合,并都显示了深卧式基础的基本特性及其与土相互作用的基本规律。
Deeply—embedded platform which consists of separated caissons snd connected bottom—beams between them has its engineering and economical advantages compared with the traditional jacket. However, the interaction mechanism of this new type of foundation with soil is still in research. In this thesis,the deeply—embedded foundation with soil under vertical and horizontal. load are analysed with three dimensional nonlinear finite element method. A parrallel model test is carried out for verification of the analysis results. The results of calculation and those of model test are principally in agreement. They both show the features and interaction characteristics of the deeply—embedded foundation with soil.
