摘　　要：文中以塔里木河为原型,通过建立物理模型和数值模型相结合的方法预测河流冲刷深度,物理模型研究表明,塔里木河南岸河道整治建筑物的最低河床水位可达海拔-60 m。沿用物理模型获得的相关参数,利用Telemac2D-Sisyphe(T2D)和River2D-MOR(R2D)对简化版南岸的侵蚀进行了数值研究。与T2D相比,R2D模型的冲刷深度模拟结果与物理模型更为一致。模型具有较强的适用性,能够很好地模拟河道冲刷的计算,可以为防汛抗旱工作提供数据支撑。Taking the Tarim River as the prototype, this paper predicted the scour depth of the river by establishing a physicalmodel and a numerical model. The study of the physical model showed that the lowest riverbed water level of the river regulationbuilding on the south bank of the Tarim River could reach -60 m under sea level.Based on the relevant parameters obtained fromthe physical model, Telemac2D-Sisyphe (T2D) and River2D-MOR(R2D) were used to conduct numerical research on the erosionof the south bank. Compared with T2D, the simulation results of erosion depth of R2D model were more consistent with the physicalmodel.The model has strong applicability, can simulate the calculation of river scour well, and can provide data support for floodcontrol and drought relief work.
