【摘要】 以最新的激光动光弹为实验手段， 对初始应力条件下的爆破应力波的传播过程进行了实验研究． 结果表明， 初始应力影响着应力波形的传播过程， 且不同的初始应力对应力波形的传播过程的影响也不相同．更多还原

【Abstract】 A new dynamic holophotoelasticity method is used in laboratory test to study propagation of dynamic stress by blasting subjected to initiative stress.The results showed that propagation of dynamic stress wave is disturbed by initiative stress, and also affected by levels of initiative stress.更多还原
