中文摘要：

针对河流冲刷造成堤岸坡脚及坡面缺损的情况建立了将冲刷预测和边坡稳定分析相结合的耦合分析方法。首先基于实测资料建立人工神经网络预测模型，对冲刷作用下堤岸及河床的变形进行预测分析，以获得堤岸坡脚被冲刷后的几何形态，然后在此基础上对边坡进行稳定分析和应力-应变分析，得出被冲刷后的边坡的整体稳定评价和变形特征。通过北江大堤某河段典型断面的计算，验证了所建立的模型和所采用的方法的有效性，对于人工堤防的运行管理具有理论意义和重要的实用价值。

英文摘要：

According to the defect of the embankment due to the river scour effect, a coupling analysis method of the river scour prediction and the slope stability analysis is established. First, based on the neural network method, the deformation prediction of the embankment and riverbed with river scour effect are made and the geometric shape of the embankment slope toe after the river scour is got. Then, the sta- bility analysis and the stress-strain analysis of the slope are carried on to get the overall stability evalua- tion and the deformation features of the embankment with river scour effect. The established model and the efficiency of the adopted method have been verified by the calculate of the typical section of the Bei- Jiang embankment. It has important theoretical basis and practical value for the operation management of the important man-made embankment.
