本文中的近海塔式结构是部分潜入海中的理想均质细长圆柱筒,上端支撑着刚性质量块,下端连接在刚性圆盘上,圆盘又附着于弹性半空间上。水被视作无旋、无粘性理想流体。本文提出一种计算部分潜入无限水域中圆柱体振动特性的解析方法,得出了水-土壤-圆柱耦联振动的固有频率、柱体振型、动水压力的解析表达式,并重点讨论了土壤变形、液面晃动、液体压缩性的影响。
The offshore tower structure in this article is an ideally homogeneous slender cylinder partially submerged into the sea. The upper end supports rigid masses, the lower end is attached to a rigid disc, and the disc is attached to the elastic half-space. Water is considered as a non-rotating, non-viscous ideal fluid. This paper presents an analytical method for calculating the vibration characteristics of cylinders that are partially submerged into infinite waters. The analytical expressions of the natural frequencies, column modes, and hydrodynamic pressures of water-soil-cylindrical coupling vibrations are derived. Soil deformation, liquid surface sloshing, liquid compressibility.
