流滑型崩岸河岸侧蚀模式初探
Preliminary study on the analytical model for slide collapse of riverbanks
摘要
Abstract
The slide collapse of riverbanks with fast -developing, large rates of bank erosion, and strong destructive powers is a common type of riverbank collapses in alluvial rivers. This type of failure is mainly caused by the direct impact of flow water, as well as resulting from the fact that water level is too close to the top of riverbanks in the course of collapse. An analytical model for the slide collapse of riverbanks is presented based on the analysis of scouring effects on the riverbanks. The model structures and parameters are evaluated using the flume experiments and centrifugal tests. The erosion coefficient of river bank is calibrated using the experimental data. The model result is in good agreement with the experiments. The analytical model contains only a few parameters and is easy to apply . The model result can be used as a reference for the prediction of riverbank erosion and channel migration.关键词
