基于量纲分析理论,分析影响边坡爆破振动速度相关物理量,推导并改进考虑高程因素影响的爆破振动速度预测公式,结合某石油储备基地山体边坡爆破开挖工程实地监测,对比分析改进公式与萨道夫斯基等传统经验公式对振动速度的预测精度。结果表明：改进公式对实测数据拟合的线性相关性为0.87,通过在公式中引入边坡坡度项（H/D）可大幅提高振动速度预测精度,垂直向质点峰值速度（PPVz）及峰值矢量和速度（PVS）预测值的最大相对误差分别为9.3%、12.7%,平均值分别为8.2%、9.8%,该公式用于边坡坡面质点振动速度预报切实、可行;PVS是坡面质点空间各方向振动速度时程信息的综合表征,综合涵盖质点3个方向振动速度分量对建（构）筑物的振动累积、破坏效应,选取PVS作为爆破振动安全控制指标更为合理。

英文摘要：

Based on the theory of dimension analysis, related physical quantities of vibration velocity at slope blasting was analyzed and blasting vibration velocity prediction formula influenced by the altitude was established. In combination with a field monitoring of mountain slope blasting excavation, a comparative analysis was made on the prediction accuracy of improved formula and traditional empirical formula. It turned out that, the linear correlation of the improved formula fitted with the meas- ured data is 0. 87, and its predication accuracy of vibration velocity is greatly increased with introduction of slope grade into the formula. The maximum prediction error of vertical Peak Particle Velocity（PPVz） and Peak Particle Velocity（PVS） are 9.3% and 12. 7% respectively,with the average prediction errors are 8.2% and 9. 8% respectively. So,the improved formula is practical and feasible to predict the particle vibration velocity of slope. PVS is a comprehensive representation of the velocity time history information of the slope particle space at each direction. The PVS covers vibration accumulation and damage effect of three components on building structures simuhaneously, so it is more reasonable to consider PVS as blasting vibration safety control index.
