摘要：

To study the mechanical evolution rule of the supporting part in the process of the reinforced concrete chimney blasting demolition, a finite element model based on a practical project is established by explicit analysis software LS-DYNA. By means of four different Angle blasting cut finite element models, the stress distribution of the supporting part and neutral axis moving rule is drawn. It will help to develop the theory of the reinforced concrete chimneys blasting demolition.
