弯道环流与沿河路基冲刷试验研究

The experiments of the circulation flow and subgrade scour in bend channel

对河弯水流形态和弯道环流的形成、发展规律以及弯道中泥沙运动特性进行了分析和试验观测 ,建立了沿河弯凹岸路基的最大冲刷深度计算公式 为沿河路基护坡和挡土墙的基础埋置深度提供了可靠依据 .

The theory analysis and experiments about the flow structure, circulation flow development features and sediment movement laws in the bend channel are made,and the formula for the maximum scour depth of the subgrade river side is established. This paper can provide scientific basis for depth of foundation of the slope and the retaining wall.
