摘要
根据河湾迎流顶冲位置和河床冲深，确定护岸范围和优选护岸护底方案。对于抛石护岸所应用的土工织物滤层的规格和国外典型实例作了介绍，并分析试验资料，给出了抛石大小和抛石落距的计算公式。
Based on the scouring position and depth by current in river bend the scope of bank protection and better selection scheme of bank protection are determined. The riprap bank protection with geotextile filter and foreign typical examples are introduced. By analyzing experimental data the calculating formulas for stone size and falling distance of riprap are given.
