爆炸加载下岩石的动态特性研究

Study of Dynamic Feature of Rock under Blasting Loading

以平面波发生器为加载源的爆炸测试系统，直接得出爆炸作用下岩石的应变历程曲线。通过对一组应变波形的Ｌａｇｒａｎｇｅ分析，指出岩石的动态特性参数值以及应变率是引起发生变化的主要原因。

In this paper a blasting measuring system which include plane-wave producer was set up to measure the strain-time curves of the rock bar under blasting loading. Other parameters of dynamic feature of Rock were calculated by Largrangian analysis method and strain is chief reason of change of parameters.
