Apparatus and method for testing combined dynamic-static loading strength of rock-like material

An apparatus for testing combined dynamic-static loading strength of a rock-like material, comprising an explosion load loading device, a static load loading device, and a stress wave rod transferring device, wherein

• the explosion load loading device is connected with one end of the stress wave rod transferring device;
• the stress wave rod transferring device is connected with a rock-like material specimen;
• the stress wave rod transferring device is connected with the static load loading device;
• the explosion load loading device comprises a hole packer provided with a wire transferring hole, an explosion load loader, a rock-like material layer, a charging hole, and a sealing cover, wherein
• one end of the hole packer is fixedly connected with one end of the explosion load loader;
• an inner cavity of the explosion load loader is filled with the rock-like material layer;
• the charging hole is provided in the rock-like material layer;
• one end of the charging hole is communicated with the wire transferring hole;
• the charging hole is filled with an explosive;
• the sealing cover is fixedly connected with the other end of the explosion load loader;
• the stress wave rod transferring device comprises a solid incident rod and a transmission rod;
• one end of the solid incident rod passes through the sealing cover and is opposite to the charging hole;
• the other end of the solid incident rod is connected with the rock-like material specimen;
• one end of the transmission rod is connected with the rock-like material specimen;
• the solid incident rod and the transmission rod are positioned on two sides of the rock-like material specimen;
• and
• the explosion load loader is filled with the rock-like material layer;
• a T-shaped mold is placed in a filling process;
• after the rock-like material layer is molded, the T-shaped mold is removed to form the charging hole and a port;
• a first end portion of the solid incident rod close to the charging hole is cylindrical, and the first end portion fits the port.
