爆炸载荷下花岗岩动态本构关系的试验研究

Experimenal Study Of Granite’s Constitutive RelationUnder Blasting Load

介绍了在爆炸载荷作用下岩石介质本构关系试验研究的一种新方法．用花岗岩石作实验材料，通过一组应变波形的量测，运用Ｌａｇｒａｎｇｅ 分析方法获得了花岗岩石在爆炸载荷下的动态本构关系曲线．并建立了爆炸加载条件下岩石动态本构关系的实验和量测系统，通过研究认为平面波发生器是更适合于作为一般爆破实验室研究动态本构关系的手段．

A new method of experimental study of rock’s constitutive relation under blasting load is introduced. By using granite as test samples and measuring a group of strain time curves of them, the granite’s constitutive relation has been calculated based on Lagrangian analysis method. The study has established the experimental system of constitutive relation of the rock under blasting load and indicates that the planewave producer is a suitable method to study rock’s constitutive relation in ordinary blasting laboratory.
