| 摘 要： | 在高强度混凝土爆炸前后,利用超声波CT成像技术,进行声波测试并生成CT图像,可以比较完整地反映混凝土的内部损伤及其变化.实验结果表明,波速的变化能良好的表征混凝土的损伤;药包爆炸后,主要在炮孔周围及其下部造成损伤,其中炮孔下部的损伤度较大,底部则受到压密作用,波速增大.

| Abstract: | The CT images before and after explosion in the high-strength concrete by using the ultrasonic CT imaging technology can reflect the internal damage of concrete and changes integrallty.The results show that the changes of wave velocity can reflect concrete′s damage well.The explosion damage are mainly around the hole and the hole bottom,especially the bottom′s damage is larger,and the wave velocity of bottom increases as ompressive effect. |
