摘　　要：为了研究化学发泡剂对水胶炸药水下爆炸能量的影响,制备了交联时间分别为0.5、1.0、3.0、24.0、72.0 h和168.0 h的水胶炸药;在相同的试验条件下,采用水下爆炸法分别测试不同交联时间下水胶炸药水下爆炸的比冲击波能、比气泡能以及总能量,并与2~#岩石乳化炸药水下爆炸总能量进行对比。结果表明,化学发泡剂对水胶炸药水下爆炸能量有较大的影响,在一定的交联时间范围内,随着交联时间的延长,水胶炸药的水下爆炸能量持续增加,当交联时间为72.0 h左右时,水胶炸药的水下爆炸能量达到最大;此后,若再延长交联时间,水胶炸药的水下爆炸能量呈下降趋势。交联时间为1.0 h时,水胶炸药的水下爆炸总能量与2~#岩石乳化炸药的水下爆炸总能量相当。Water gel explosives were prepared at various crosslinking time of 0.5,1.0,3.0,24.0,72.0 h and 168.0 h to study the influence of chemical foaming agent on its underwater explosion energy.Their shock wave energy,bubble energy,as well as the total energy were tested under the same experimental conditions.The total underwater explosion energy was compared to that of 2~#rock emulsion explosive.Results show that chemical foaming agent has a great inf-luence on underwater explosion energy of water gel explosive.The underwater explosion energy of water gel explosive increases with the extension of crosslinking time,reaches to the maximum value at about 72.0 h,and then declines.At the crosslinking time of 1.0 h,the underwater explosion energy of water gel explosive is equivalent to that of 2~#rock emulsion explosive.
