浅水域爆炸冲击波传播特性

Propagation Rule of Explosion Wave in Shallow Water

通过浅水域炸药裸露爆炸试验,实测得到水中爆炸波典型波形及峰值压力数据,分析了水中冲击波传播特性与衰减规律;对冲击波峰值压力进行线性回归分析,给出了浅水域爆炸冲击波衰减公式;在此基础上,通过有限元分析软件ANSYS/LS-DYNA进行数值模拟,进一步验证并总结了部分相关结论。部分结论成果已应用于福建漳州古雷航道二期疏浚项目。

By the experiments of bare explosives in shallow water,the waveform curves and pressure data of shock wave were tested. The characteristics and the law of its propagation of shock wave in water produced by the explosion were analyzed. Through linear regression analysis,semi-theory-semi-experienced formula of the shock wave on this condition was given and verified. The numerical simulation was executed by finite element analysis software ANSYS / LS-DYNA. Some conclusions were verified and summarized. Some of the conclusions have been applied to the second dredging project at Gulei Port in Zhangzhou,Fujian province.
