为了了解砂与橡胶粒隔震垫层下隔震结构的抗倾覆特性，以砂与橡胶粒混合隔震垫层、纯砂隔震垫层、非隔震三种情况作为研究对象，建立4组高宽比为1．0，2．0，3．0，4．0的框架结构模型。通过抗倾覆性振动台试验，分析在不同垫层类型、垫层厚度、加速度峰值条件下的上部结构的抗倾覆性能。试验结果表明：结构的抗倾覆性能在砂与橡胶粒隔震垫层下要优于纯砂隔震垫层，非隔震情况下的抗倾覆性能最弱；当加速度峰值加大时，结构的抗倾覆性能随之降低。

Taking sand and rubber particle hybrid isolation cushion and pure sand isolation cushion and non-iso-lated as the research object, 4 groups of frame structure models with length-width ratio of 1.0, 2.0, 3.0, 4.0 were established respectively.The anti-overturning performance of the superstructure under different cushion types, cushion thickness and acceleration peak was analyzed with anti -overturning shaking table test.The ex-perimental results showed that the structural anti-overturning performance of the sand and rubber particle hybrid isolation cushion is better than that of pure sand isolation cushion, and the structural anti-overturning perform-ance of the non-isolated cushion is the weakest.With the increase of peak value of the acceleration, anti-o-verturning performance of the structure decreases.
