摘　　要：针对刚性结构存在限制其适应局部冲刷变形的不足,进行柔性促淤结构的研究,并提出一种仿生型柔性促淤护滩结构。采用动床水槽试验方法研究仿生型柔性促淤护滩结构在不同来流条件下、不同布置方式下的减速促淤效果,结果表明其效果良好。将研究成果运用于汉江河口段航道整治工程中,进一步检验研究成果。结果表明其该结构整体性较好,应用区工程效果与模型试验数据总体一致,达到护滩促淤的预期目标。该结构丰富了航道整治工程促淤结构形式,具有较好的应用前景。Considering the difficulty of rigid structures in adapting to local scour deformation, we study the flexible siltation-promoting structure and propose a bionic flexible siltation-promoting beach protection structure. The structure’s effect of erosion prevention and siltation promotion is investigated under different inflow conditions and arrangement modes by movable bed experiments in flumes, the result of which shows a satisfactory effect. Applying the research results to the waterway regulation project of the Hanjiang River estuary, we further test the research results by field application. The results indicate that the structure has good integrity. In addition, the engineering effect in the application area is consistent with the model test data, and thus the expected goal of beach protection and siltation promotion has been achieved. This structure enriches the siltation-promoting structure forms in waterway regulation projects with a good application prospect.
