| 摘 要： | 为了研究江河崩岸的发生机理,以长江中下游及其他河流典型崩岸实例为依据,分析了江河崩岸的影响因素及其对崩岸的作用,并针对崩岸类型分析了崩岸的关键性影响因素.结果表明:岸坡土体物质组成及分布和岸坡局部地形是崩岸形成的主要内在因素,水流冲刷和地下水渗流是崩岸形成的主要外部动力因素;各因素对崩岸的作用主要表现为侵蚀破坏、渗流破坏、重力破坏及突加荷载或边界条件破坏等.

| Abstract: | In order to study the mechanism of bank collapse,the influencing factors as well as their effect on the bank collapse were analyzed based on some collapse cases in the middle and lower reaches of Yangtze River and other rivers.The key influencing factors for the bank collapse were discussed with regard to its collapse types.The results show that the composition and distribution of soil and the local topography of bank slopes are the main internal factors,and the erosion flows and groundwater seepage are the... |
