摘要

根据岩石爆破特征,利用柱状空腔膨胀理论对爆破产生的弹塑性区的应力分布进行了研究,给出了弹塑性区内应力分布的解析表达式。借助于爆炸力学近似计算公式,验证了应力在弹塑性区的分布,理论计算结果表明,理论计算值与近似计算基本一致。





Abstract

Applying the theory of cylindrical cavity expansion, the characteristics of distribution of stress in elastic-plastic zones are studied according to behavior of blasting-induced deformation of rock. The distribution of stress expression of theory is presented. The stress value is validated by the theory of classical explosion mechanics. The results of theoretical calculation analysis keep good consistence with that given by traditional mechanics.
