摘　　要：通过物理模型试验,研究方形薄壁生态护岸结构不同孔隙率条件下的水力特性。结果表明:不同孔隙率下水面线变化趋势基本一致;孔隙率越大,护岸区内水流减速效果越好;紊动强度和孔隙率呈正相关性;护岸前、后断面剪切应力沿横向分布规律基本一致,整体上呈先增大再减小的趋势,纵向分布平顺,剪切力大致相同。The hydraulic characteristics of a square thin-wall ecological revetment structure under different porosity conditions are studied by the physical model test.The results show that the variation trend of water surface profile is basically the same under different porosity conditions.With the increase of porosity,the deceleration effect of water flow in the revetment area turns better.There is a positive correlation between turbulence intensity and porosity.The transverse distribution law of the shear stress in the front and rear sections of the revetment is basically the same,and it increases first and then decreases on the whole.The longitudinal distribution of the shear stress is smooth,and it is almost the same.
