摘要
在水下爆破中,爆破产生的水中冲击波对鱼类的伤害最大,但目前尚未形成一个公认的安全控制标准。本文通过对试验实测成果和有关文献资料的分析,认为鱼类承受水中冲击波的能力不仅与鱼类的品种有关,还与鱼类的生活环境有关。对于石首鱼科鱼类的水中冲击波超压安全控制标准应小于0.05MPa;对于处于自由状态的非石首鱼科鱼类,和处于约束状态如网箱内的非石首鱼科鱼类分别以0.30MPa和0.20MPa作为水中冲击波超压安全允许标准。
When underwater blasting is carried out, shock wave in water caused by blasting is biggest damage to fish, but there is no generally accepted security control standard. Based on the analysis of actual test measurements and relevant literature, it was considered that fish＇s ability to withstand shock wave in water was not only relevant with their species but also with their living environment. For Sciaenidae fish, security control standard of shock wave in water should be less than 0.05MPa; for non-Sciaenidae fish being free, 0.30MPa can be as their safety standard to endure shock wave in water; and for non-Sciaenidae fish being constrained such as caged non-Sciaenidae, 0.20MPa can be as the safety standard to shock wave in water.
