装药长径比对坑道中冲击波峰值压力影响的试验
The results indicate that: the cavity radius becomes stable at approximately 6000μs;the blasting pressure waves mainly are transmitted horizontally;the peak pressure has a negative logarithm relationship with distance perpendicular to the charging bisector;and the valid influence area r.
应用ANSYS/LS-DYNA有限元程序对条形装药黄土地基中爆炸过程进行了三维数值模拟,发现在6000μs爆炸空腔已基本稳定,条形装药爆炸产生的压力波以水平方向传播为主,装药中垂线方向爆炸产生的峰值压力与离中垂线距离呈负对数关系,土的有效影响范围半径大约为爆炸后形成的空腔半径的4倍。
The experimental results show that the peak pressure and positive pressure actuation duration by the first drilled explosion on the same measuring points are less th.
