摘　　要：分析了冲击波超压测试及TNT的等效威力,计算了爆炸高度及距离对超压测试结果的影响,给出了马赫杆对测试结果的作用,而这在以往的测试中经常被忽略。通过试验验证了提出的计算方法,两者之间的平均误差为3.1%。根据该计算方法,通过超压测试数据可以很方便地得到爆炸的等效TNT当量,从而直接为工程技术人员使用。The measure method of shock wave overpressure and TNT equivalent of the explosion was analyzed, the influence of the explosion height and distance on the test results has been calculated, and the function of Mach pole to the tests, which is usually neglected previously, was given. The calculation method was verified by overpressure tests, and the error between them is 3.1%.Through the overpressure tests combined with the calculating method, the TNT equivalent of the explosion effect could be gotten conveniently for engineers.
