Study on Damage of Concrete Dam Subjected to Combined Action of Earthquake and Slide Surge

Abstract:

It is possible for hydraulic engineering located in high intensity earthquake area under the action of extreme disaster induced by earthquake and secondary slide surge. Several impact action models of slide surge were introduced and the damage evolution of concrete gravity dam subjected to combined action of different sequences of earthquake and secondary slide surge were studied based on nonlinear numerical analysis. The effects of different time sequences of combined earthquake and slide surge were compared and the safety performance analysis was performed. The results show that the combined form has great effects on the damage evolution law of concrete gravity dam.
