分段装药结构爆破效果的数值模拟研究
Numerical simulation of structure performance under blasting with piecewise charge
摘要
Abstract
This paper numerically simulates the stress development and generates a three-di-mensional model of the medium-deep hole blasting in infinite rock mass for continuous charge and divided charge in blasting by using the large-scale nonlinear dynamic analysis software LS-DYNA and the elastic-plastic model*MAT_PLASTIC_KINEMATIC and JwL. The difference of the decreasing rate in Von Mises effective stress of blasting,element effective stress peak in free face,the bore wall stress and acceleration are investigated. It is shown that divided charge could greatly improve the blasting effect by engineering blasting practice.关键词
