岩体的震动或爆炸荷载导致了瞬时荷载的产生，而由此产生的应力状态将是动态的或准静态的。
Rock vibration or explosion load lead to the instantaneous load, under these circumstances, stress is at dynamic or quasi-static.
研究表明，荷载瞬时作用后，地基中有明显的有效应力变化，这是地基产生初始沉降的原因。
From the analysis, it is found that the changing of the effective stress in the ground results in the immediate settlement.
另外，应力与瞬时应变线性拟合结果表明，瞬时轴向应变与轴向荷载近似成比例增长。
In addition, results of the linear regression for stress and instantaneous strain show that the instantaneous axial strain and axial load approximated to grow proportionally.
爆炸发生在结构内部时，结构受到双重荷载作用：瞬时的冲击波荷载和长时间的准静态气体压力。
When explosion took place inside structures, the structure bore dual load: the transient shock wave and long duration quasi-static gas pressure.
