| 摘 要： | 针对萨道夫斯基公式不能反映钻孔爆破自由面尺寸影响的不足,提出了可体现自由面面积对爆破震动强度产生较大影响这一特点的钻孔爆破振动速度计算公式.通过人和场隧道掘进爆破的实测数据检验,钻孔爆破振速公式的准确率比萨道夫斯基公式高80%,且对于质点振动速度大于0.5 cm.s-1的测点,其相对误差不超过5%的测点数达90%以上.实测数据检验表明,提出的钻孔爆破振速简化计算公式,明显优于萨道夫斯基公式,且计算简便,更适合于工程应用. |

| Abstract: | In view of the shortage of Sodev's empirical formula which doesn't involve the free surface area,the calculating formula of vibration velocity in drilling blasting is put forward which can reflect the characteristics of the free surface area affecting the seismic intensity of blasting.Based on the actual data in tunneling blasting of Re Hechang tunnel,the accuracy of the calculating formula is higher than that of the Sodev's empirical formula by 80% and for the measuring points of the vibration velocity greater than 0.5cm/s,the ratio of measuring points whose relative error value given by the calculating formula is less than 5% exceeds 90%.Based on the actual data,the simplified formula is put forward which more easily adapts to the needs of engineering.Comparison results of the simplified formula with that of the Sodev's empirical formula show the results of the simplified formula are closer to the actual values. |
