摘　　要：为满足广大农村地区推广复合隔震技术的需要,在钢筋-沥青复合隔震层的基础上,开发了一种水平-竖向复合隔震墩,其能同时有效减轻水平地震作用和竖向地震作用对上部结构的影响。介绍了该隔震装置的构造、工作原理和设计理论,并以刚体质量块代替刚度较大的砌体建筑物,对水平-竖向复合隔震墩进行振动台模拟地震试验。结果表明,此复合隔震装置吸收了大部分地震能量,减震效果明显且造价低廉,适合于广大农村地区推广使用,具有良好的经济和社会效益。In order to enlarge the application of base isolation technology in rural area, based on the steel-as- phalt isolation layer, the lateral and vertical composite seismic isolation pier is proposed to overcome the short- comings of complex construction and inconvenient volume production. Design process and working principle of the device are introduced. With rigid mass block in place of low building with larger rigidity, the simulated test on shaking table is carried out. The results show that the composite isolation pier can absorb most of the seismic energy, damping effect is obvious ,with low cost, suitable for rural areas.
