摘要
在不同的爆破条件下,在大理岩中进行了模拟爆破实验。在对爆破损伤岩石的力学特性进行实验研究的基础上,得到了在不同爆点距离和爆破条件下,爆破对岩石损伤作用的一些规律,并应用岩石弹脆性细观损伤模型,对爆破损伤岩石的细观裂纹扩展规律及其损伤特性进行了分析。
The experiments are made in marble to simulate blast in different conditions. On the basis of experimental study on the mechanical properties of blasting damaged rock, the regularities of rock damage by blasting are obtained in different distance and blasting conditions. Finally, both the spreading regularities of meso-crack and the damage properties of blast damaged rock are analyzed by applying an elasto-brittle meso-damage model for blast damaged rock.
