| 摘 要： | 通过对2008年四川省汶川8．0级特大地震时天水台记录到的地震波形进行分析，结果发现：龙门山断裂带在汶川特大地震后，天水台记录到的余震出现了3—4秒的地震波速异常，认为与此次特大地震后龙门山断裂带的破碎有关。

| Abstract: | The seismic waves of Wenchuan 8.0 earthquake in 2008 recorded by Tianshui station were analyzed, and the results show that 7 -8 seconds seismic velocity anomalies appeared in Longmenshan fault zone after the event, and this may be related with the fragmentation of the Longmenshan fault zone. |
