中文摘要：

文章以ANSYS／LS-DYNA有限元软件为基础，针对工程实际中所采用的起爆方法，计算了在一定条件下，不同起爆方式的柱状装药在岩石中的爆炸作用，探讨了柱状药包在不同起爆方式下的应力场及端部效应等特征，为工程应用和安全施工提供参考。

英文摘要：

Based on ANSYS/LS-DYNA, and aimed at the initiation way of cylindrical charge in practical project, the blasting effects of cylindrical charge in rock were simulated under different ways of initiation in this paper. The blasting characters such as stress field and end-effect of cylindrical charge in the different initiation way were discussed. The results obtained offer a reference for the application and safety of blasting projects.
