摘要
通过分析节理岩体的结构特征，建立了节理岩体的质量综合评价指标体系，并将其嵌入ＤＹＮＡ２Ｄ程序框架，用数值计算方法模拟了岩体中的节理对爆破作用的影响。
In this paper,the structured characteristic of jointed rock masses is analyzed overall,and its quality synthetic evaluation target system is built.In the meantime,the quality synthetic evaluation is brought into the DYNA 2D program,numerical calculation to be carried out.Guiding practice of engineering blasting with the simulation results,it provides the theoretical basis to jointed rock masses by blasting.
