摘要:
针对由岩石堆砌的防波堤结构，采用试验与数值模拟相结合的方法，探究不同装药量与不同装药埋深下的防波堤毁伤情况。研究结果表明：增加装药量和装药埋深均可增强对防波堤的爆破毁伤效果。装药量1 kg时，埋深10 cm比无埋深的爆坑直径、爆坑深度与裂纹区直径分别增加1.11、 0.41、 0.95倍；埋深20 cm比无埋深的爆坑直径、爆坑深度与裂纹区直径分别增加2.08、 2.18、 1.97倍。装药埋深20 cm时，装药量2 kg比装药1 kg的爆坑直径、爆坑深度与裂纹区直径分别增加0.57、 0.28、 0.21倍；装药量3 kg比装药量1 kg的爆坑直径、爆坑深度与裂纹区直径分别增加0.63、 0.35、 0.51倍。可为实际爆破工程和军事作战提供参考。
Abstract:
A combination of experiments and numerical simulations was used to investigate the damage of breakwaters built with rock piles under different charges and burial depths. The research results indicate that increasing the charge amount and burial depth can enhance the blasting damage on breakwaters. When the charge amount is 1kg, the diameter of the explosion pit, the depth of the explosion pit, and the diameter of the crack zone increase by 1.11, 0.41 times and 0.95 times respectively with a buried depth of 10 cm compared to those without burial depth. The diameter of the explosion pit, the depth of the explosion pit, and the diameter of the crack zone increase by 2.08, 2.18 times and 1.97 times respectively with a buried depth of 20 cm compared to those without burial depth. When the buried depth of the charge is 20 cm, the diameter of the explosion pit, the depth of the explosion pit, and the diameter of the crack zone increase by 0.57, 0.28 times and 0.21 times respectively with a charge amount of 2 kg compared to those with a charge amount of 1 kg. The diameter of the explosion pit, the depth of the explosion pit, and the diameter of the crack zone increased by 0.63, 0.35 times and 0.51 times respectively with a charge amount of 3 kg compared to those with a charge amount of 1 kg. It can provide references for practical blasting engineering and military operations.
