摘要
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。
Earthquake frequency is generally higher in the mountain reservoir area, and many earthquake is sequences earthquake. In order to ensure safety of the dam＇s quality and the operation, the monitoring of dam is essential. When an earthquake occurs, the destruction of dam is generally inspected from the macro phenomenon. From micro terms, monitoring and analysis to stress - strain and seepage state of the discharge structures, the impact of the earthquake on the dam safety and safety impoundment of the reservoir is determined by the means of the using prototype observation.
