Zusammenfassung:	The invention relates to a device and a method for testing static and dynamic direct tensile strength of annular core. The device comprises: two fixed bearing platforms with fixed guide rails are fixedly connected to the left part and the right part of the upper end of a bottom support seat at intervals. The press-pull transfer mechanism consists of a sliding bearing platform, a transfer block and a loading unit. The lower end of the sliding bearing platform is provided with a chute. The inner end of that transfer block is provided with a guide inclined plane. The loading unit consists of a strip-shaped connecting block and a semicircular loading head. The left and right sides of the lower end of the wedge-shaped loading block are provided with loading inclined planes, the lower end of the wedge-shaped loading block is arranged between the upper ends of the two transfer blocks.
