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。
Using the dilatancy characteristics of the material when it enters the damaged state and the change of the material structure and the velocity of the elastic wave caused by the explosion, a strain brick is set in the model body to measure the volume strain of the material during the explosion and measure the deformation of the model material Wave velocity. The test results show that in the model of the explosion test, similar to the real rock explosion can be obtained under the destruction of the area, the application of these two methods to simulate the test of explosion model body damage area is valid and reasonable, for correlation Provide the experimental basis for the analysis.
