提出了一个预测潜在冲击载荷下振动效应的理论模型与现场实测相结合的综合预测方法。通过一系列具有针对性的室外重锤冲击振动试验，以及现场实测数据对Anderson模型进行了验证并修正，然后利用修正的Anderson模型预测冲击荷载的振动效应。将预测结果和现场试验结果进行对比分析，结果表明：预测结果与实测结果吻合较好。
提齣瞭一箇預測潛在遲擊載荷下振動效應的理論模型與現場實測相結閤的綜閤預測方法。通過一繫列具有針對性的室外重錘遲擊振動試驗，以及現場實測數據對Anderson模型進行瞭驗證併脩正，然後利用脩正的Anderson模型預測遲擊荷載的振動效應。將預測結果和現場試驗結果進行對比分析，結果錶明：預測結果與實測結果吻閤較好。

A synthetic method which combines theoretical model and field measurement data was put forward to predict vibration effects induced by impact loading. A series of targeted field measurements were proceeded by hammer impact tests. The Anderson model was modified and verified by the data measured in field hammer impact tests. Then the impact induced vibration was predicted using the modified Anderson model. Finally,the prediction results were com-pared with the measured results. The results indicate that the prediction results approximately approach to the measured results.
