摘要
介绍了隔震技术原理,对电厂碎煤机室隔震结构在7~9度的抗震性能进行分析,并与常规结构的抗震性能以及经济性进行对比。隔震技术通过延长结构周期以及提高结构阻尼比,大幅度减小地震作用,结构具有良好的抗震性能,分析了由于隔震产生的较大位移对电厂工艺方面的影响。
The principle of seismic isolation technology was introduced.The seismic performance of the isolation structure of the coal crusher room of the power plant at 7~9 degrees was analyzed and compared with the seismic performance and economical efficiency of the conventional structure.Seismic isolation technology greatly reduces the effect of earthquakes by extending the period of the structure and increasing the damping ratio of the structure.The structure has good seismic performance.The impact of the large displacement due to isolation on the power plant process was analyzed.
