流滑型窝崩特征及概化模拟试验

Lab test study on mechanism of bank flow-induced slide with nest shapein the middle and lower reaches of the Yangtze River

    摘要
  • 摘要: 流滑型窝崩是长江中下游一种典型的岸滩崩塌形式,土体崩塌破坏发展速度快、体量大,危害很大.根据典型实例,分析了此类崩岸的特征和发生规律,并通过初步的概化模拟试验,探讨了其形成过程和成因机理.研究结果表明,流滑型窝崩是水流冲刷过程中引起的土体滑动破坏,岸坡土质抗冲差、近岸水流急是窝崩形成的基础条件,而伴随窝塘扩大出现高强度的回流是土体连续崩塌破坏的重要动力因素.

     

    Abstract: The flow-induced slide with nest shape is one of typical bank collapses in the middle and lower reaches of the Yangtze River.It is considerably harmful to many aspects in river engineering with fast speed and large quantity of soil failure.By some case studies,its characteristics and occurrence rule are analyzed in this paper.A lab test of flow-induced slide with nest shape is performed to research bank failure formation process and its mechanism.The model test results show that flow-induced slide is a soil...
