摘要:
基底隔震技术是减小结构地震响应的一种有效方式.本文以“华龙一号”某核安全相关厂房为工程背景,开展基底隔震技术的工程设计与研究.本文从厂房概况、地震输入参数、基底隔震布置方案和隔震支座性能参数的确定入手,对隔震层安全性分析、隔震结构自振特性、隔震结构减震效果等方面分别进行了论述.通过分析研究发现,采用隔震技术能够有效降低结构及其附属设备的水平向地震响应,提高结构及其附属设备的抗震安全裕度,有利于高烈度地震地区核电厂的选址建设.作为国内首次将基底隔震应用于核电厂中的核安全相关厂房,本研究为后续核电厂的隔震设计与研究提供了良好的工程借鉴意义和有益的设计经验.
Abstract:
Base isolation technique is an effective way to reduce the seismic response of structures.In this paper, the engineering design and research of base isolation technology are carried out based on the engineering background of a nuclear safety-related plant in Hualong One.Starting from the determination of the general situation of the plant, the seismic input parameters, the base isolation layout scheme and the performance parameters of the isolation bearing, the safety analysis of the isolation layer, the natural vibration characteristics of the isolation structure and the damping effect of the isolation structure are discussed respectively.The analysis shows that the seismic isolation technology can effectively reduce the horizontal seismic response of the structure and its auxiliary equipment, improve the seismic safety margin of the structure and its auxiliary equipment, and is beneficial to the site construction of nuclear power plants in high-intensity earthquake areas.As the first application of base isolation in nuclear safety-related plant in China, this study provides a good engineering reference and useful design experience for subsequent nuclear power plant isolation design and research.
