摘　　要：崩岸是长江中下游河道平面变形的主要形式之一,会对防洪安全、航道畅通、涉水工程安全运行及河势稳定等产生影响。护岸工程是长江中下游防洪体系、河势控制和河道整治工程的重要组成部分,在防洪保安、稳定河势与改善通航条件等方面发挥了重要作用。新的水沙情势下长江经济带高质量发展的战略格局、长江大保护和以人为本的生态绿色发展理念对长江中下游河势稳定和护岸工程技术提出了更高的要求。在系统总结长江中下游河道河床演变特性和趋势、崩岸机理及监测预警、护岸工程技术成果的基础上,对长江中下游崩岸机理与护岸工程技术进行了回顾与展望。该工作对于贯彻落实长江经济带建设的国家战略、提高长江流域防灾减灾应急预警能力和保障中下游沿江地区乃至全流域经济社会的高质量发展具有重要意义。Bank collapse plays a key roles in the channel deformation in the Middle and Lower Yangtze River(MYR and LYR), which could cause serious problems to the flood management, navigation safety, safe operation of the riparian hydraulic works and could affect the stability of river regime. As an important part of the flood control system, bank protection engineering on preventing the flood disasters, stabilizing the river regime and improving the navigation conditions. However, the high-quality development of the Yangtze River Economic Belt(YEB), the grand protection of the Yangtze River, the vision of people-oriented ecological green development have put forward higher requirements on the bank protection engineering in the MYR and LYR. The current research results are systematically reviewed the achieved progresses in channel bed evolution characteristics and trends, mechanisms, monitoring and early-warning of bank collapse, and bank protection technology in the MYR and LYR. The future prospect on the bank collapse mechanisms and bank protection technology were also conducted. This research is of great significance for implementing the national strategy of the development of the YEB, improving the capabilities of disaster prevention and relief,emergency response and early-warning in Yangtze River basin, and ensuring the high-quality development of economy and society in the MYR and LYR and even the whole basin.
