摘要
采用数值模拟手段,针对减震沟爆心距、长度、深度、宽度4项参数,采用不同参数值进行了多组模拟。模拟数据反映了不同参数对减震沟减震效果的影响规律,模拟结果表明:除减震沟宽度外,减震沟爆心距、长度、深度对于减震沟的减震效果均有显著影响。该数值模拟成果有助于减震沟在工程中的合理运用。
By using the numerical simulation method, groups of simulation experiments with different parameter values have been carried out especially for four parameters including the distance, length, depth and width from ditch to blast hole. The simulation data reflects the influence of different parameters on damping effect of damp ditch. The simulation results indicated that： except for the width, the distance, length and depth from ditch to hole of damp ditch have significantly influence on the damping effect. The achievement is useful for proper use of damp ditch in engineering.
