摘　　要：通过对比试验,对我国村镇量大面广的单层实心砖墙房屋的抗震加固方法进行研究。制作了1/4缩尺的未设防模型和抗震加固模型,分别进行了模拟地震振动台试验,对模型在地震作用下的地震反应和震害现象进行对比分析。试验结果表明,对既有单层实心砖墙房屋采取抗震加固措施,可以有效提高房屋的综合抗震能力,减轻地震破坏。Through contrast experiment, the seismic strengthening methods of single-storey brick-wall building in villages and towns are studied. Two 1 ： 4 scale models of this kind of building are designed and tested on shaking table, one of them is non-fortification model, another is seismic strengthening model. Based on the experiment, the seismic performance and earthquake disaster phenomena of them are contrasted and analyzed. The results show that the seismic performance of single-storey brick-wall building can be improved effectively by taking seismic strengthening measures.
