| 摘 要： | 为了论证12位数字强震仪在性能和价格上具有优势，在一个水库大坝内安放了3台12位数字强震仪。期间记录到云南永胜ML6．1级地震和盐源宁蒗ML5．8级地震，结果仪器观测到的谱峰值都在0．80－0．86之间；最大加速度为1．14（伽）。12位数字强震仪能够满足大坝监测要求，而且价格便宜。

| Abstract: | To prove 12 - digital accelerometer to be capable of using in monitoring the running of reservoir dam, we put three sets of meters in a reservoir dam. During the operation of the meters, two earthquakes, Yongshen ML6.1 Earthquake and Yanyuan - Ninglang ML5.8 Earthquake, were recorded. The peak values of frequency spectrum are between 0.80 and 0.86 and maximum peak value is 1.14 gal. Our work shows that the 12 - digital meter of strong earthquakes can be used to monitor the running of reservoir dam and the meter is cheap. |
