评述了数值模拟技术在拆除爆破中应用的重要性，回顾了拆除爆破数值模拟的主要方法，论述了各种方法的优缺点。结合工程应用实例介绍了笔者及团队研发的离散元框架内的网格实体模型。分析了当前拆除爆破数值模拟技术存在的主要问题，对拆除爆破数值模拟技术的进一步发展进行了展望。

The applications of numerical simulation in demolition blasting were reviewed. Several methods of numerical simulation in demolition blasting were introduced. The strength and weakness of the numerical methods mentioned in this paper were also indicated，respectively. Furthermore，the solid lattice model in the frame of discrete element method（DEM），which was developed by the author and his team，was detailed described. The existed problems in the current numerical simulation methods of demolition blasting were presented and the future trend of the numerical simulation is finally prospected.
