摘　　要：作为地冲击效应的重要组成部分，感生地冲击效应对地下防护工程设计与分析至关重要。常规装药不同埋深爆炸地表空气冲击波超压的确定，是进行侵彻爆炸感生地冲击参数传播规律研究的前提。通过现场试验，研究了岩石中装药埋深对地表空气冲击波超压的影响，提出了不同埋深爆炸地表空气冲击波超压峰值影响系数概念，并建立了该影响系数的计算公式，给出了不同埋深爆炸地表空气冲击波超压峰值的预计方法。As an sign and analysis important component of ground shock effects, the induced ground shock effect is important for the de of underground protective engineering. To attain the overpressure of surface air shock wave induced by conventional explosion at different buried depths is the foundation of the study on propagation rules of induced ground shock parameters. Through site tests, the influence of buried depth of charge on the overpressure of surface air shock wave is researched, the concept of influence coefficient of explosion at different buried depths to the overpressure of sur face air shock wave is introduced, the calculation formula of the coefficient is built up, and the estimating method of the overpressure of surface air shock wave induced by explosion at different buried depths is provided.
