摘要

利用材料进入破坏状态时具有的剪胀特性及爆炸造成材料结构改变和弹性波波速会发生改变的特性，在模型体内设置应变砖，测量爆炸时材料的体积应变，并测量爆腔附近模型材料的波速。测试结果表明，在模型化爆试验中，可以得到与实际岩体爆炸情况下相似的破坏区，应用这两种方法监测模拟化爆试验模型体的破坏区是有效和合理的，可为进行相关的分析提供试验依据。

Abstract

When material bearing explosive dynamics load is in failure state

it has the shear dilatancy behaviors

at the same time

the material structure and the elastic wave velocity are changed. The material volume strain and the velocity near explosive cavity are measured using strain gauge embedded in model body and acceleration sensor. Measuring results show that

in the model test

the similar failure rock zone area as reality under the explosion circumstance is obtained; the measuring methods are effective and reasonable

when it is used to monitor failure area in explosive model test and it can provide experimental basis for related analysis.
