摘　　要：介绍对瀑布沟水库用加卸载响应比和波速比监测预测水库诱发地震的实践过程,通过课题以往的预测和对应其后期实际发生的地震来分析,结果显示:地震频度库水加卸载响应比Yn和Cr值、库水下方地震波速比这两种方法都可以作为监测预测水库诱发地震的新方法。The paper described the application of load-unload response ratio and wave velocity ratio in monitoring and forecasting earthquakes induced by the Pubugou reservoir. From the previous forecasts and the corresponding earthquakes that actually occurred, the paper did analysis. The results show that frequency of earthquakes and load-unload response ratios（Ynand Cr）and wave velocity ratios under a reservoir can both be used as new methods to monitor and forecast induced reservoir earthquakes.
