摘要
混凝土水下爆破需要的炸药单耗与露天爆破相比存在很大差异。通过10个混凝土试件陆地和水下爆破效果的对比分析,探讨了在25—30 m水深作用下炸药单耗的增量问题。得出在25 m左右水头时,为达到同样的爆破效果炸药单耗应较陆地爆破增加2—4倍。
Compared with blasting open fields,there is tremendous difference in unit volume consumption of dynamite underwater explosion of concrete.The paper analyzed and compared the effect between underwater and open fields by the blasting of 10 concrete samples,investigated the unit volume dynamite consumption underwater 25—30 m.The conclusion is drawn that the unit volume dynamite consumption must be increased by 2—4 times in 25 m underwater than that on open fields.
