岩石爆破光弹性损伤模型实验研究

Experiment Study on Damage Photoelastic Model of Rock Fragmentation by Blasting

通过损伤材料的光弹性分析，提出了利用损伤光弹性材料进行岩石爆破机理研究的新方法。通过实验，摸索出损伤光弹性材料制作的可行措施，得到了可用来进行光弹性试验研究的光弹性材料，并对材料的力学性能以及爆炸作用下损伤对材料中应力波的影响及其相互作用进行了研究。

Accoding to the photoelastic analyses of damage model, a new method is put forward to study the rock fragmentation mechanics; the damage photoelastic material is made and the method is feasible;The effect of damage on the static mechanic property, the distribution of stress field and propagation of blasting wave, also the mutual action between wave and damage are analyzed.
