摘要

采用土工数值分析方法

对水流冲刷过程中的河岸崩塌问题进行了分析。分析了水流冲刷引起的河岸后退距离及后退过程中坡内的渗流情况与坡体的稳定性;探讨了水流冲刷过程中岸坡崩塌的发生机理;指出了坡内的渗流作用与坡前水流的冲刷作用是岸坡发生崩塌的主要动力因素

而岸坡土体的物质组成和分布、岸坡坡度等则是岸坡发生崩塌的主要内在因素;并提出了相应的工程防护措施。

Abstract

Bank failure under lateral erosion is analyzed by numerical method. A method to calculate lateral erosion distance is put forward. With continual lateral erosion seepage and stability of bank have dynamic changes. Mechanism and cause of bank failure under lateral erosion are put forward. The seepage and erosion are primary dynamic influence factors on bank failure; and the soil composition

soil distribution and slope angle of bank are primary internal influence factors on bank failure. Based on mechanism analysis relevant treatment measures to bank stability are presented.
