摘要
空心圆台插板组合结构体作为一种新型防洪护岸构筑物,它通过撕裂、分散和阻滞冲刷河岸(包括河床)的水流,大大减轻水流的冲刷强度,以达到防冲促淤的目的。通过理论分析、数值模拟及水槽实验对该结构体的护岸机理进行探讨,并对结构体群进行阻力实验研究,为空心圆台插板组合结构体群护岸技术的推广应用提供依据。
The bollow circular truncated clone witb plates plugged on is a novel structure for flood control and bank protection. This structure can help to prevent erosion or even contribute to deposition by ripping, dispersing and blocking the flows which scour the river banks （including the river bed）. Based on a theoretical analysis, numerical simulations and flume experiments, the effects on flow condition and thc characteristics of drag force of this structure are discussed. This research undoubtedly provides an important basis for the generalization and application of the new bank revetment structure.
