中文摘要：
为了研究洲滩守护工程的护滩效果及工程实施后局部冲刷坑形态，以长江下游较为典型的洲滩守护工程为例，采用大比尺局部动床概化物理模型试验方法，对鱼骨型间隔式护滩带工程进行了试验研究。根据工程及试验具体情况，详细分析了该试验方法的可行性，并给出了鱼骨型护滩带方案的试验结果。结果表明，该试验方法不但能够较方便地比选不同平面布置的工程方案之间的护滩效果，同时可得到局部冲刷坑的形态参数，对工程设计有较好的指导意义。
英文摘要：
In order to research the effect of river beach protection engineering and scour hole reduced by the engineering, we take a typical river beach protection engineering as an example and set a large-scale local movable bed generalized model to research the fishbone type beach protection engineering. According to specific conditions of the model experiment, we analyze the feasibility of this method and give the model result of fishbone type beach protection engineering. The results show that this method can not only compare the beach protection effect among different engineering layout plans easily, but also get the morphological parameters of local scour hole, which gives a better guidance to the engineering design.
