摘要
介绍了一个砖烟囱拆除的爆破实例,并在爆破前运用DDA程序对爆破效果进行了数值模拟,结果表明:模拟计算和实际爆破在倾倒过程和爆破效果等方面具有很好的相似性,从而可进行爆破效果的爆前预测,对爆破设计、施工和安全防护等具有指导意义。
Demolition of a brick chimney by directional blasting is introduced. Using the DDA software, the numerical simulation of blasting is realized. The research shows that the simulative result accords with the practical result in the course of blasting. In addition, the simulative result can be used to predict and direct blasting.
