摘要
文章针对一种新型海上风机基础型式的单柱复合筒型基础的承载特性,在砂土中进行了小比尺物理模型试验。试验中采用了位移控制的水平单调加载方式,选择加载速度与压载为变量,得到水平承载力荷载位移曲线。试验结果表明,基础极限承载力与加载速度和压载质量均呈正相关。得出了基础在加载过程中不同舱内孔隙水压力的变化规律。
A small-scale physical model test was conducted in sandy soil to investigate the bearing characteristics of a mono-column composite bucket as a new type of offshore wind turbine foundation.In the experiment,a displacement controlled horizontal monotonic loading method was used,and the loading speed and pressure were selected as variables to obtain the horizontal bearing capacity load displacement curve.The experimental results show that the ultimate bearing capacity of the foundation is positively correlated with the loading speed and ballast mass;Summarized the variation law of pore water pressure in different compartments of the foundation during the loading process.
