基于水流动力作用的河道岸坡稳定性能分析

摘要

Based on hydrodynamics,taking Shandong river bank slope as an example,the effect of slope on the hydrodynamic variation was analyzed with water dynamics-soil mechanics slope analysis method.The results showed that:different types of slopesoil erosion by rivers Effect varying in degrees ,the size larger is more eroded;Based on hydrodynamic effects,slope stability analysis method can form a more realisticreflection of slope as well as the stability of the variation with time.%以水动力学为基础，以山东某河道岸坡为例，采用水动力学-土力学边坡分析方法分析了岸坡在水流动力作用下的变化规律。分析结果表明：不同土质类型的岸坡受到河流冲刷作用的影响程度不同，粒径越大的土质越易受到冲刷，基于水流动力作用的岸坡稳定性分析方法能够更为真实的反映岸坡形态以及稳定性随时间变化的规律。
