【摘要】 海洋工程油气开发逐步向深海域进军 ,资料表明 2 1世纪深海的石油、天然气将是主要能源之一。目前主要的深海石油平台形式是张力腿平台 ,其结构一般由平台本体、张力腿系统和基础系统三部分组成。基础部分不但承受着结构上部及海底的各种载荷 ,而且为结构提供必要的稳定性和安全性。本文通过对当今世界已建成投产的 9座深海张力腿平台及其基础形式进行分析 ,剖析它们的基础设计思想 ,为我国深海张力腿平台的设计提供参考。更多还原

【Abstract】 WT5”BZ]With the development of ocean engineering, oil and gas will be the main natural energy resources in the present century. There are broad sea reginons in China. Exploration shows that there are plenty of gas and oil in the South China Sea. Therefore, it is important to exploit the deep water. The Tension Leg Platform (TLP) has been found suitable for working in the deep water due to its favorable motion characteristics and low cost. Recently, TLP is used as the main platform in the deep water. It consists of three parts:hull, tendons and foundation. The foundation is an important part which affecs the stability and safety of the whole structure. In this paper, TLPs that have been constructed in the world are analyzed including the design of their foundations. Some useful conclusions and proposials can be referred to in the design of TLP in China. [WT5HZ]更多还原
