混凝土重力坝基础扬压力的动态变化可对大坝的安全运行产生不利的影响。针对日调节水库大坝下游水位变幅大的特点，将传统的扬压力统计模型加以改进，使改进后的模型考虑了下游水位变化对扬压力变化的滞后效应。工程实例计算表明，改进后的模型更有效、拟合精度更高。

Abastract:The dynamic change of concrete gravity dam foundation uplift pressure can produce adverse effect to the safe opera-tion 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.
