摘　　要：针对历次地震造成我国村镇房屋大量倒塌的震害特点,研究一种用于村镇低矮砌体结构房屋的橡胶垫隔震技术,为验证本文设计的橡胶隔震支座对低矮砌体结构房屋的隔震效果,获得相应的技术指标和参数,完成了1片未设置隔震支座的砌体墙对比试件和3片设置不同规格隔震支座砌体墙的拟动力试验。研究设置不同参数的隔震支座在模型结构中、经历不同强度地震波激励时的抗震性能和受力破坏过程,验证隔震措施及隔震构造的有效性,为进一步的研究和应用提供试验依据。研究表明,GT-3和GT-4墙体试件分别在相当于9度和10度中震强度的模拟地震波下未发生破坏,所设置的隔震支座达到了预期目标,GT-2试件所设置的隔震支座未能达到预期目标,还应做进一步调整。In view of the characteristics of collapsed rural houses in a large number in previous earthquake disasters,a kind of rubber isolation technology for rural low masonry structure building is studied.In order to test for vibration isolation effect of the rubber isolation bearings which is installed in low masonry structure buildings and obtain the corresponding technical indicators and parameters,the pseudo dynamic test of three pieces of masonry wall with different specifications of isolation bearings and one piece of masonry wall without isolation bearing in contrast are carried out.The seismic performance and failure process of the model structure with different isolation bearings in the motivation of different seismic intensity are analyzed,the effectiveness of the isolation measures and structural measures is verified,experimental basis is provided for further research and application.The research shows that,GT-3 and GT-4 specimen can resist earthquakes in 9 and 10 degrees effectively and the isolation bearings installed make the goal,while the isolation bearings installed in GT-2 specimen cannot achieve its goal and should be adjusted.
