摘要(Abstract):
微粒优化支持向量机对爆破振动强度的预报能力优于经验公式法。比较高程差、水平距离、段药量、总药量、台阶高度、孔排距、抛掷方向和底盘抵抗线等8个输入参量不同组合的预报结果发现:前三个参量的组合预报效果最佳,预报相对误差仅为3.21%。
Support vector machine with particle swarm optimization algorithm is superiority over the empirical formula method on the prediction ability of blasting vibration intensity.Comparing the prediction results of different combinations of eight input elements such as height difference,horizontal distance,maximum charge,total charge,bench height,hole and row spacing,cast direction and batholithic resistance line,the combination of the former three elements was found to give best results,with the relative error being only at the level of 3.21%.
