摘　　要：水位变化是影响堤防稳定安全的重要影响因素,为了定量分析赤田港堤防在不同水位变化条件下的迎水侧堤坡稳定安全,考虑水位变化速率影响,对堤防迎水侧进行堤坡稳定有限元计算。分析赤田港堤防在不同水位变化速率、堤坡比和冲刷深度影响下堤坡稳定安全的变化规律,对赤田港现状堤防结构优化和除险加固措施选取具有指导意义。The change of water level is an important factor to affect the stability of dikes.In order to quantitatively analyze the stability of the Chitiangang dikes'waterward slopes under different water level changes,finite element calculation of dike stability was conducted for the waterward slope with the consideration of the influence of water levels'change rates.It is instructional to analyze the change rules of Chitiangang dikes under different water level change rates,embankment slope ratios,and erosion depths for the optimization of the current dike structure and the selection of reinforcement measures for Chitiangang dike.
