| 摘 要： | 作为海洋平台的基础部分,吸力式桶形基础除了承受海洋平台结构及自身重量等竖向荷载的长期作用,还要承担风、波浪等扭剪荷载作用,但目前对于吸力式桶形基础的扭剪承载力尚缺乏合理的计算模式和分析方法.针对软黏土横观各向异性,采用有限元数值分析方法,研究了扭剪荷载作用下桶形基础承载性能,据此进行了一系列变动参数比较计算,并对大量的... |

| Abstract: | As the part of offshore platform,the suctional bucket foundation bears not only the vertical loading induced by the weight of offshore platform structure and itself but also torsion shear loadsing induced by wave and wind.However,there is no a commonly-acceptable calculation mode and analytical method for the torsional shear of suctional bucket foundation.According to the transversely anisotropy of soft clay,the bearing performance of bucket foundation is studied under the condition of tortional shear loadi... |
