摘要
针对海洋环境引起的桩基平台的振动,提出采用叠层橡胶支座为其生活模块进行隔振。对简化后的计算模型进行了理论分析,给出了水平限位措施和支座稳定性的校核方法。通过算例计算,研究了隔振效果,以及支座水平刚度、外激励频率与生活模块响应的关系。
Laminated rubber bearing is utilized for vibrating isolation on accommodation module of pile foundation platform, which is excited by ocean environment. This paper gives dynamic analysis about simplified mode of platform, then level stopper of bearing and computational formula of bearing stability are presented. Finally
it studies isolation efficiency, the relations are obtained among level stiffness of bearing, ocean exciting frequency and maximum response of accommodation module.
