摘　　要：对岩石爆破地震波作用下底层框架砌体结构进行了动力分析 ,建立了爆破地震波作用下底层框架砌体结构的非线性时程分析方法。并利用某水电站地下厂房开挖爆破的地震波 ,对其周边的 1栋 1托 5底层框架砌体结构 ,进行了实例分析 ,通过与构造地震波作用下结构的动力反应进行了对比 。A dynamic analysis of hybrid masonry-concrete structures encountering the blasting seismic wave is presented. The time-history analysis method of hybrid masonry-concrete structures encountering the blasting seismic wave is set up. Meanwhile, using the blasting seismic wave in a excavating underground workshop of a hydropower plant (Fujian province), a nearby six-floor hybrid masonry-concrete structures were analyzed. Lastly, a security evaluation is made by comparing the results of the dynamic responses under earthquake waves.
