山区水库区域地震发生频率一般较高,而且很多为序列地震,为保证水库大坝在序列地震影响下,大坝质量安全及运行管理安全,对水库大坝受地震影响进行监测必不可少。在地震发生时,一般从宏观上,对大坝的破坏情况进行巡检,微观上,对大坝运用原型观测手段,对大坝及泄水建筑物应力应变、渗流状态等进行监测分析,通过监测分析,来判断地震对大坝安全的影响,以及地震对水库的安全蓄水造成的影响。
The frequency of earthquakes in mountain reservoirs is generally high and many of them are sequence earthquakes. To ensure dam safety and operational safety under the influence of sequence earthquakes, it is essential to monitor the impact of earthquakes on reservoir dams. At the time of the earthquake, the damage of the dam was generally inspected macroscopically. On the microcosmic, the prototype observation method of the dam was used to monitor and analyze the stress, strain and seepage conditions of the dam and the dike, Monitoring analysis to determine the impact of earthquakes on dam safety and the impact of earthquakes on the safe storage of reservoirs.
