Abstract: Abastract:The dynamic change of concrete gravity dam foundation uplift pressure can produce adverse effect to the safe operation of dam.In view of the daily regulation reservoir dam downstream of the characteristics of large variation range of water level,the traditional uplift pressure statistical model is improved,the improved model takes into account the downstream water level changes of uplift pressure time delayed-response.Engineering example calculation shows that:the improved model is more effective and has higher fitting precision.
