摘要
本文通过数值仿真方法研究了海洋导管架平台在不均匀支撑条件下的桩腿承载能力变化规律。不均匀高度的离散性显著影响支撑腿的最大承载力,呈现出显著的空间相关性衰减特征;桩腿支撑高度的合理分布,将有效提升承载体系对导管架组块的整体承载能力。
This paper investigates the variation law of leg bearing capacity for offshore jacket platforms under non-uniform support conditions through numerical simulation methods.The discreteness of non-uniform heights significantly affects the maximum bearing capacity of support legs,exhibiting obvious spatial correlation attenuation characteristics.The rational distribution of leg support heights can effectively enhance the overall bearing capacity of the bearing system for jacket modules.
