| 摘 要： | 本文研究了桩在竖向荷载和横向荷载作用下承载能力的计算模型，给出了单桩承载能力的概率分析以及不同支承条件对海洋平台结构体系承载能力的影响；提出了具有结构－桩－土相互作用的海洋平台结构体系承载能力的概率特性和在极端荷载作用下海洋平台结构体系的可靠度计算方法。研究结果表明：对于桩支承海洋平台结构体系的承载能力，结构－桩－土相互作用的影响是不容忽视的，其偏差影响取决于土性的离散度。

| Abstract: | In this paper, calculation model of pile load bearing capacity under vertical and horizontal olads is researched, probability distribution of load bearing capacity of single pile is given, and also the effect of different supporting on offshore platform structure system is discussed. Probability properties of load bearing capacity of the system considering the structure pile soil interaction and its reliability under extreme loads are presented. It is shown that this interaction effect on load bearing capacity of pile supporting structural system can mot be meglected and that it's deviation effect depends on the diversity of soil. |
