| 摘 要： | 以某电站地下厂房楼板结构为例,采用计算模拟法对抽水蓄能电站常用的板梁和厚板结构进行计算,并对其不同楼板结构的动力特性进行了对比分析.结果表明,当厂房楼板的静力刚度要求较高时(板梁结构静力刚度等效于1.5 m厚板结构),板梁结构自振频率高、动力响应小,其结构形式优于厚板结构;当厂房楼板的静力刚度要求不高时(板粱结构静力刚度等效于1.0 m厚板结构),板梁和厚板结构的动力特性相差不大.

| Abstract: | This paper presents a numerical simulation of the underground powerhouse floor structure of a pumped storage power plant.It indicates that the plate girder structure has static stiffness equivalent to the 1.5 meter thick plate structure,and therefore is superior to the latter in meeting higher requirement in static stiffness with its higher self-vibration frequency and less dynamical response.However,it also shows that both types have similar dynamical property when static stiffness is not highly required(s... |
