摘　　要：针对新疆某天燃气工程指挥部的抗震问题,对其采用隔震技术进行加固,并采用“抱柱托梁加垫”和“夹墙梁”的方法进行施工,确保其上部结构安全。采用国际通用的三维空间有限元软件ETABS对其进行建模分析,并用时程分析方法对其进行隔震加固设计分析。在此基础上,分析了其减震效果,并介绍了本工程采用的施工工艺及相应的关键技术。结果表明:该工程隔震加固效果比较显著,能较好地满足现行规范和使用功能的要求,故对其进行隔震加固设计与施工是可行的。In view of the seismic problem of the gas engineering headquarters in Xinjiang Province,the seismic isolation technology was adopted to strengthen the headquarters,and the methods of“pad the column joist”and“clamp the wall beam”were adopted for construction to ensure the safety of its superstructure.Based on the method of time history analysis of seismic isolation and reinforcement,the structure was analyzed by ETABS,an internationally accepted three-dimensional finite element software.On this basis,the damping effect is analyzed.The construction technology and the corresponding key technologies adopted in this project are also introduced.The results show that the isolation effectiveness is relatively remarkable and it can better meet the requirements of the current norms.Therefore,it is feasible to design and construct the base isolation reinforcement.
