摘　　要：基于河道崩岸现有研究成果,对崩岸类型的划分进行了梳理,进而将河道崩岸的影响因素概括为水流动力条件、河道边界条件,及其他因素3大类,并从数值模拟和概化模型试验2个方面总结了河道崩岸研究的进展。在此基础上,分析讨论了当前河道崩岸机理研究中存在的不足,如未能全面考虑各种因素影响、崩岸数值模拟技术不够完善、概化模型试验精度需进一步提高等。最后,对未来崩岸研究工作的开展,提出了需关注的重点与建议。On the basis of previous research results of river bank collapse,we reviewed the classifications of bank collapse types,summarized the influencing factors of river bank collapse into three categories inclusive of flow condition,river boundary condition,and other factors.We further concluded the research progress of river bank collapse from aspects of numerical simulation and generalized model test.Furthermore,we analyzed and discussed the deficiencies of current research on the mechanism of river bank collapse.Such deficiencies are:factors are not considered comprehensively enough;numerical technologies lack perfection;and the accuracy of generalized model needs to be improved.Last but not the least,we put forward the key points and suggestions for future research work.
