|
摘要
通过靶场实验 ,探讨了不同地形条件下爆破地震波幅值的传播特性 ;研究了隔震沟尺寸、深度、位置等因素对隔震效果的影响 ;观测了不同隔震沟尺寸条件下爆破地震波的幅值 .实验得出 ,隔震沟的隔震作用与爆源位置、爆源距离、爆源能量和隔震沟本身的尺寸有关 .爆源距离越远、能量越小以及隔震沟位置越低、尺寸越大 ,则隔震效果越明显
The propagation characteristics of the amplitude of the blasting seismic wave under the conditions of various topographies are approached by means of experiments. Some factors affecting the effects of quake insulation groove, such as the size, the depth and the position of the quake insulation groove, 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.
