对自然分层堤岸冲蚀过程机理进行了论述,据此能估算堤岸的冲蚀率。从阿拉河河漫滩开挖的沟槽中发现,冲蚀过程分为3个阶段:一是堤岸非粘土层冲蚀;二是上部挂空的粘土层受拉崩塌;三是水流冲碎崩塌下来的土块并随水流冲走。根据动力因素提出了上部粉砂上崩塌和水流挟带的崩塌土块的估算方法。
The mechanism of erosive natural delamination embankment is discussed, which can estimate the embankment erosion rate. It is found that the erosion process is divided into three stages: one is embankment non-clay layer erosion; the other is that the upper hanging clay layer is pulled and collapsed; the other is that the water flows and crushes and collapses Cakes and washed away with the water. Based on the dynamic factors, the method of estimating the collapse mass of the upper silt and the entrained collapse mass of the water flow is proposed.
