| 摘 要： | 采用动Winkler弹性地基梁模型模拟桩土问动力相互作用，并考虑了流体与桩问相互作用，通过组合成层土中、水中桩单元的刚度阵，推得了独桩海洋平台连续系统横向振动的动刚度阵及在波浪力作用下平台甲板处的频率响应函数，进而求得了在确定性波浪力及随机波浪力作用下桩身任意点的位移响应。最后，通过算例研究和分析了在随机波浪力作用下成层土参数、甲板上重量及冲刷淘深等因素对平台振动响应的影响。

| Abstract: | The lateral dynamic stiffness matrix and frequency response function of a single pile supported offshore platform are obtained by means of combining all the pile elements stiffness matrixes solved from the calculated models of pile, soil and fluid, in which the interaction of pile and soil is modeled as a dynamic Winkler medium and the fluid-pile interaction is considered. Thus the dynamic response at an arbitrary position along the pile under determinate or stochastic wave loading can be obtained. Then the influences of some parameters such as layered soil shear modulus, equipment mass on the deck and the depth of scooping on the dynamic behavior of the single pile platform under wave force action are discussed through a calculation sample. |
