摘　　要：对水下爆炸中自由场压力的水面截断效应及冲击载荷与船体相互作用的船体壁压进行了分析,得出了自由场压力的水面截断效应及早期的船体壁压计算近似公式,并与实际水下爆炸试验测量结果进行了对比。从试验测量中还可以看出,在迎爆面上同一点的舰体壁压峰值约为自由场压力峰值的1.4到1.8倍,舰体壁压反射系数与冲击波的入射角度有关。The water truncation effect of frce-field pressure and the wall pressure of ship under impact load are analyzed in this paper,and the frce-field pressure equation with water intercepting effect and the approximate equation of ship wall pressure are also obtained, which are compared with the measuring result of underwater explosion experiment. According to the measuring results,the peak value of wall pressure is 1.4 to 1.8 times to free-field prossure at the position facing the spot, and the reflection factor of ship is influenced by the incident angle of shock wave.
