摘要
运用动力有限元方法分析爆炸波作用下三相饱和水土中不动刚性障碍物上的波动荷载。计算结果表明,不动刚性障碍物上的波动荷载不仅与空气含量有关,而且与作用荷载的波形及大小有关。其反射系数不同于非饱和土中的情况,最大反射系数可以远大于2.0。
In this paper, dynamic finite element method is used to investigate thewave loading on fixed rigid obstacle for explosive loading in three- phase waterloggedsoil. Calculations demonstrate that the wave loading on fixed rigid obstacle is not onlyrelated to the content of air , but also related to the waveform of loading.The maximumreflecting coefficient can be much more than 2.0 , it is very different from that of nonsaturated soil。
