摘要：

When an accidental explosion in a surface magazine is happened, the three primary events : air blast, ground shock and debris, may be produced. To protect surface structures and/or human life from these events, the magazine can be constructed in a subsurface. However, the safety distances and design criteria for a subsurface magazine have not been defined yet. In a series of explosion tests, this study is to examine the effects of overburden and charge mass to structure volume ratio on the blast pressure resulting from an accidental explosion in a subsurface magazine. In tests, the air blast pressure propagated along the ground surface was measured by the blast pressure sensors. From the small scale test, it has been found that the blast pressure from a subsurface magazine increases with the increase of charge mass to structure volume ratio. Furthermore, the value of peak pressure has been formulated as a function of the charge mass to structure volume ratio.
