Antiseismic supporting base body

Abstract

An antiseismic supporting base body, which has a bearing platform on its upper surface and a main foundation below the bearing platform, wherein the main foundation has an antiseismic body, the surface area of the external surface of the antiseismic body is decreased continuously or discontinuously from top to bottom, and the strongest antiseismic strength of the antiseismic body is located in the central axis of the antiseismic body. By means of both the shape and the strength distribution of the antiseismic supporting base body, the impulse of the earthquake wave to the antiseismic body is dispersed so that the antiseismic ability increases. Also the friction between the antiseismic supporting base body and the stratum increases, and the ability of the antiseismic supporting base body to bear the external load and the stress resulted form the load raises.
