【摘要】 封闭空间爆炸工程要求以最小的空间来约束爆炸效应,因此关心百MPa以上的爆炸冲击波荷载,经典爆炸著作都未深入讨论这一区域的爆炸荷载规律,即便部分著作提供了这一区域的荷载数据,因为未能提供可靠实测数据背景,其可信度仍然有待实验证实。这几年,笔者开展了"封闭空间的化爆荷载与沙墙消波"专项实验研究,获得了一批实验数据,对近区化爆荷载、沙墙消波效果和封闭空间化爆准静气压产生了一些新的认识,就这些情况作一介绍。更多还原

【Abstract】 Strong shock wave loads over 100 MPa produced by chemical explosion in enclosed space involves enclosure explosion engineering.The shock wave in this pressure region has not been discussed deeply in the classic literatures.Although a few works have provided the data of shock wave in this pressure region,their reliability are not confirmed due to the lack of the experimental condition.The investigation of "Explosive Load in Enclosed Space and Attenuating Shock Wave by Sand Wall" was in recent years,and a set of test data were obtained.更多还原
