Experimental research on amplitude change of blasting seismic wave with topography

The propagation characteristics of the amplitude of the blasting seismic wave under the conditions of various topographies are examined by means of experiments. The effects of the size, the depth and the position of the quake insulation groove on isolation effect, are studied. The amplitudes of the blasting seismic waves under the conditions of the different sizes of the quake insulation groove are measured. According to the experiments, the effects of the quake insulation groove are related to the position, the distance, the energy of the explosion source and the size of the quake insulation groove itself. The farther it is from the explosion source, the smaller the energy is. The lower its position is and the larger its size is, the more remarkable the effects of the quake insulation groove are.
