| 摘 要： | 在分析关于水流作用下斜坡上块石起动理论的基础上,从研究斜坡上单个块体出发,利用水流作用下异形块起动的极限平衡条件,推导出了异形块体平均粒径的计算公式,并由此设计了两种混凝土异形块和一种钢筋石笼的形状、尺寸及工程布置形式.结合工程实际,简述了混凝土异形块及钢筋石笼的施工机理及效果.与传统护岸形式相比,钢筋石笼和混凝土异形块防冲护岸具有漂距小、精度高、固冲作用显著等优点,特别适用于迎流顶冲的崩岸强度大的河段.

| Abstract: | Based on an analysis of the initial motion theory of rock mass lying on slopes under flow action, a formula was derived for calculation of the average diameter of heteromorphic blocks according to the ultimate balance condition. With the formula, the shape, size and configuration of two kinds of concrete heteromorphic blocks and one kind of reinforced gabions were designed. In combination with practical projects, the mechanism and effectiveness of concrete heteromorphic blocks and reinforced gabions in construction were briefly introduced. Compared with the conventional bank protection measures, the method has the advantages of relatively short drifting distance, high precision, and good effect of scour prevention, and is specially suitable for the river section with serious danger of bank collapse. |
