Description

限位减隔震系统及方法 技术领域
本发明属于土木工程技术领域，涉及一种限位减隔震系统及方法。
背景技术
在土木工程建设领域中，特别是海上升压站、海上变流站、高柔结构等，由于地震作用、风浪流耦合作用引起的上部平台振动、偏转等，会对上部主体结构以及相关的设施安全和正常使用性能造成极大的损伤，通常需要采取设置减隔震系统的方法，释放支座顶部位移和上部结构的转动应力，实现消耗能量达到减震隔震的目的。目前，我国已建成的海上升压站基础形式一般采用单桩基础、多桩基础、导管架基础以及高桩承台基础等，但是当前上部主体结构与下部支撑结构的连接一般采用的是刚性连接，不利于整体结构的抗震，也不能降低海洋环境中风浪流耦合作用对基础的循环往复作用产生的不利影响。
