中文摘要：

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。

英文摘要：

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.
