The ground vibration input method based on viscous-spring boundary simulates the incidence of plane SV and P waves at different angles, and the acoustic structure coupling method is used to simulate the dynamic water pressure inside the lock chamber to study the seismic response of the lock roof displacement, acceleration and plastic damage in the ultra-high head lock chamber at different water depths. The study shows that when the seismic waves are obliquely incident, the seismic response of the ultra-high head locks varies significantly with the water depth compared to the vertical incidence, and the general degree of seismic response is greater than that of the vertical incidence. Under the same water depth conditions, the peak horizontal relative displacement and peak horizontal acceleration of the top of locks increases with the increases of the incidence angle in most cases. The seismic response of the lock chamber structure of the ultra-high head lock is significantly affected by the variation of the water depth. The area near the general gate wall with relative height of 0.2 is more likely to have serious damage, and when the relative water depth is 0.97, the tensile damage range on the waterfront side of the gate wall reaching serious damage is the largest. It is suggested that the combined effect of oblique incident seismic waves and different water depths within the gate should be considered.
