摘  要:长江中下游河道崩岸频现,现阶段主要采用护岸达到守护岸坡、防治崩岸的目的。为探究崩岸频发河段内有效、经济的护岸布置形式,借助试验手段对比分析理想梯形顺直河道中不同守护高度及不同护岸结构的守护效果。试验表明:排体护岸更利于持久稳固,但应重视坡折点现象;重点守护岸坡上部在有限时间内更能起到有效防治崩岸的作用,且随着守护宽度的增大,守护效果越显著;从护岸布置的有效性及经济性出发,一般情况下守护岸坡上部2h/3的高程范围较为合理。Bank collapse occurs frequently in the middle and lower reaches of the Yangtze river, so revetments are arranged to protect slopes and prevent the bank from falling at this stage.To search an effective and economic layout of revetments in the regions where bank collapse occurs frequently, we use tests to analyze protecting results of different heights and different structures of revetments in ideal trapezoidal and straight river.The test shows that row bank revetments are more conducive to long-term stability if it is single arranged,but we should pay attention to the phenomenon of slope break point; revetments arranged in the upper regions of slopes get better effects in the limited time; with the width of revetments increased,effects are more obvious; from the effectiveness and economy,revetments arranged in the upper regions of slopes around 2 h/3 height are more reasonable.
