以实验室及现场模型试验中观察到的溃堤机理为基础，开发了一个无粘性土（沙）堤的溃堤模型。模型用现场试验的数据校准，又用实验室试验的数据进行验证，计算与观测值间的拟合结果令人满意。模型还对一个溃堤实例进行了模拟，计算结果与目测报告基本一致。

Based on the mechanism of breach erosion observed in various tests in the laboratory and field, a mathematical model for breach growth simulation in noncohesive-dikes (sand-dikes) has been developed. The model has been calibrated with the data of a field experiment and verified with the data of a laboratory experiment, yielding good agreement. The model has also been used for simulation of the failure of a prototype dike, computed results are more or less in agreement with an eye-witness report.
