| 摘 要： | 介绍河道堤防设计高程的概率和风险校核方法。该方法综合考虑多种不确定性因素的影响，利用随机微分方程推求河道水位的概率分布，并对风浪的随机影响进行分析，按照随机可靠性理论，对常规采用确定性方法确定的河道堤防高程进行漫顶风险校核和可靠性设计。

| Abstract: | Probability distribution of river water levels is derived by use of the stochastic differential equations through considering the effects of various uncertainty factors, and the stochastic effects of wind waves are analyzed. According to the stochastic reliability theory, the overflow risk of river embankment elevation determined by conventional certainty methods is checked, and the reliability is designed. |

| Keywords: | risk analysis reliability design river embankment elevation wind wave |
