摘要: 坝基扬压力的大小直接影响大坝的稳定。通过实测资料,对坝基总扬压力建立数值模型,结合小概率法计算,对大坝在确定概率水平下的最大扬压力值进行估计。实例表明,该方法切实可行。

Abstract: Uplift pressure of dam affects the dam stability. This paper presents an analysis method for calculating the utmost uplift pressure beneath dam by a numerical model based on observed data in combination with probabilily computation.An illustration shows that it is feasible for evaluating the utmost uplift pressure of dam with certain probability level.
