【Abstract】 This paper proposes a practical and effective seismic isolation technology be made of steel and asphalt.To study the seismic isolation effect of the isolation layer,shaking table tests are performed for specimen heights and different acceleration amplitude input by shaking table. It introduces the design process and the construction technique about the steel-asphalt isolation layer,and field tests are performed to verify the technical reliability and usefulness. The results show that the steel-asphalt isolation layer with simple construction method,local materials and low cost can effectively reduce acceleration response under earthquake,and it is very suitable for seismic areas around the world.更多还原
