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.

Key words: shear dilatancy theory, elastic wave velocity, explosive model test
