    摘要:The safety evaluation of earthquake-damaged arch dam is very important
       for the assessment of seismic performance and failure risk after
       earthquake. The nonlinear numerical analysis was performed to study the
       water pressure overloading performance of arch dam damaged by earthquake
       of different intensities. The displacement variation with water pressure
       of earthquake-damage arch dam was discussed and the after-earthquake
       safety was analyzed by proposed damage area ratio and damage volume
       ratio. The results show that: the body configuration and bearing
       mechanism make arch dam possess excellent seismic performance,and the
       water pressure bearing capacity of damaged arch dam after earthquake can
       be guaranteed if the dam can bear the earthquake action. The proposed
       accumulative damage area ratio and volume ratio can reflect not only the
       evolution of seismic performance of arch dam,but also the water pressure
       bearing safety of damaged dam after earthquake and are more suitable as
       indexes of arch dam safety performance.
