摘　　要：刚性护岸如模袋混凝土、浆砌石等具有强度高、稳定性好、抗冲刷能力强、不透水、不变形等优点,是一种很有效的护岸技术[1、2],但在护岸岸脚处却容易产生淘刷,从而导致岸坡失稳[3]。以试验为基础,对刚性护岸岸脚水流的流态、特性进行了研究,探讨刚性护岸岸脚淘刷的机理。Rigidity revetment such as bag-formed concrete is a kind of valid hank protection technique, with high intensity, good stability, strong anti-scouring, impermeable, and anti-deformation. However, rigidity revetment has the unsteady phenomenon due to scouring at the base of revetment, which results in the easy eroding of the bank slope. In this paper, based on experiment, the flow and characteristics near the bank base is researched, and the mechanism for bank base eroding of rigidity revetment is discussed.
