Landslide surge could cause severe damage to dams, and the risk grows higher when the landslide surge happened during the earthquake. In this paper, the reasonable surge pressure model is chosen though analyses. With the example of the Koyna concrete gravity dam, the damage caused by both earthquake and landslide surge was discussed. Numerical results show that, at the same landslide surge height, the landslide surge overlapped with earthquake at different moments cause different damage to dam. The damage at upstream face caused by both landslide surge and earthquake is much larger than that caused only by earthquake. Source
