# 基于ANSYS的预裂爆破减振效应数值模拟研究Numerical Simulation Research of Damping Effect Caused by Blasting Vibration in Pre-Splitting Engineering Based on ANSYS

Because of the instantaneity, ambiguity and diversity of related factors in the process of pre-split blasting, ıt is impossible to solve this problem by using experimental means. Based on a typical project, calculation and analysis of vibration effect are made by means of numerical simulation of pre-split blasting in this paper. The roduction process of the stress wave and the rule of pre-crack propagation are researched, and the damage range of surrounding rock is determined. The results show that vibration reduction rate is about 90% for 10 cm wide pre-crack.
