摘要
通过对国内某重力坝坝段进行振动台模型破坏试验,研究了大坝在遭遇不同强度地震时的损伤破坏与大坝特性参数之间的关系,探求了损伤判别和定位的方法,以期为大坝的健康诊断提供技术参考。
In this paper,based on the shaking table test of a gravity dam in China,the relationships between the damage and characteristic parameters of dam under different intensity earthquake were studied,and the methods of damage identification and location were also explored,which could provide technical references for health diagnosis of dam.
