摘　　要：通过对水中爆炸激波在水泥净浆试样中传播的数值模拟,再现了爆炸激波的传播过程,采用对典型单元受到的激波作用和应力进行分析的方法,得出了水泥试样各个区域损伤破坏的成因,数值模拟结果和实验现象吻合。Propagation of the blast wave in cement sample in the water was simulated. The damage causes of different areas in cement sample were explored by using the method analysizing the blast wave and stress acting on typical cement sample element. Numerical results are in agreement with the experiment.
