概述地震工程中的隔震研究是近些年来发展较快的一种抗震新对策。在国外已有不少研究成果,有些工业发达国家已在不少重要的结构物,例如核电站、桥梁、建筑结构等以及某些重要设备,例如核电站的管道系统、泵、阀门等实际安装了各种形式的隔震装置。我国的一些单位也已经开展了这方面的研究工作,有的己经取得一些成果。在地震荷载作用下,结构的惯性运动引起了结构及结构内部的敏感设备对于地面的相对位移,这种相对位移往往是结构或设备损坏的重要原因。而结构或设备的破坏严重程度主要依赖于其自身的动力特 Overview Seismic research in seismic engineering is a new anti-seismic strategy that has developed rapidly in recent years. There have been many research achievements in foreign countries. Some industrialized countries have already installed various important structures such as nuclear power plants, bridges, building structures, and certain important equipment such as pipe systems, pumps, and valves of nuclear power plants. A kind of isolation device. Some units in our country have also carried out research work in this area, and some have achieved some results. Under the action of seismic load, the inertial motion of the structure causes the relative displacement of the sensitive device inside the structure and structure to the ground. This relative displacement is often an important cause of structural or equipment damage. The severity of structural or equipment damage depends mainly on its own
