摘要(Abstract):
爆破振动速度是表征和评判地震强度必不可少的参量,结合某核电站一期地面爆破振动监测数据,分析比较了爆破振动速度的3种预测方法(地震动经验公式法、基函数回归法、BP算法),并讨论了炸药类型、最大药量、炮孔直径、最小抵抗线和延时间隔对爆破振动速度的影响,为工程实践控制爆破振动危害提供了理论依据。
The blasting vibration velocity is an essential parameter to characterize and assess the seismic intensity.On the basis of monitoring data from the ground vibration of bench blasting near a running nuclear power plant,three kinds of predictive methods of vibration velocity(empirical formula method the ground vibration,basic function regression method,Back-Propagation Algorithm) were analyzed and compared and influences of explosive types,maximal charge,bore-hole diameter,minimal resistance line and delay interval on blasting vibration were discussed,which provided theoretical basis for controlling damage caused by blasting vibration.
