摘　　要：粉细砂河床岸坡由于受到洪水剧烈的冲淤作用,导致河道频繁改动,修建护岸工程是防止河岸淘刷、稳固河道的重要措施。河水对护岸工程基础的淘刷是工程稳定的薄弱环节,也是造成工程破坏的最普遍因素,因此粉细砂河床上护岸工程基础的防冲结构设计是保证工程安全稳定的关键环节。以塔河主要支流阿克苏河下游某堤防护岸工程为例,介绍了该护岸工程在处理粉细砂岸坡基础中较为成功的防护结构型式,对护岸工程的淘刷机理和基础防护结构进行了分析,并对工程基础冲刷深度计算和护脚结构重要技术指标的选取提出探讨和建议,为此类工程建设提供一定的参考。Due to the severe scouring and silting of flood towards the silty sand bank slope,the river channel changes frequently.The construction of bank protection project is an important measure to prevent the scouring and brushing and to stabilize the river.The scouring and brushing of bank revetment project foundation by river water is the weak link of project stability,and also the most common factor causing project damage.Therefore,the design of anti-scour structure of bank revetment engineering foundation on silty sand riverbed is the key link to ensure the safety and stability of the project.In this paper,a bank revetment project of a levee in the lower reaches of the Aksu River,the main tributary of the Tahe River,is taken as an example to introduce the successful protection structure type of the bank revetment project in the treatment of silty sand bank slope foundation.The scouring mechanism and foundation protection structure of the bank protection project are analyzed,and the calculation of the scouring depth of the project foundation and the selection of the important technical indexes of the foot protection structure are discussed and suggestions are put forward,which can provide some reference for such project construction.
