摘要
Abstract
A combination of experiments and numerical simulations was used to investigate the damage of breakwa-ters 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 diam-eter 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.关键词
