摘要
自升式平台是近海石油开发中最主要的移动式平台,被国内外广泛使用。通过对现役自升式平台的结构特点进行分析,简要介绍了自升式钻井平台的分类、桩靴形状和桩土相互作用中的穿刺现象;探讨了国外对桩土相互作用机理的研究情况,重点阐述了国外对桩土相互作用的实验研究和土体本构模型的发展及数值模拟方法;而后对国内的研究情况进行了总结,提出了在自升式平台桩土相互作用方面应该深入探讨的问题。
Jack-up platform is the main type of mobile platform in the offshore oil development. And it is widely used at home and abroad. The structural characteristics of the jack-up working on the sea, are ana- lyzed. The classification of the jack-up,.the shape of the pile and the punch-through phenomenon are intro- duced. The research works on the pile-soil interaction mechanism, especially the experimental studies and the numerical simulation are discussed. And finally, the problems on the pile-soil interaction mechanism, which should be further investigated, are issued.
