摘要
将边坡结构简化成二维模型进行计算分析时,边坡形状对其简化结果产生影响,为此从边坡的平面形状和边坡高度2个方面着手,用三维数值模拟对边坡稳定性进行分析,计算结果表明:坡顶曲线半径对边坡稳定性影响较大。在进行边坡稳定性分析时,应首先根据坡顶曲线半径大小界定是否可以将边坡简化为二维模型。
To determine the influence of slope shape on the simplification of slope structure into a two-dimensional calculation model,a three-dimensional numerical simulation was conducted from the plane shape of slope and its height,to analyze the stability of slope.The result shows that the curve radius of slope top has a great influence on the stability of slope.Therefore,when making a stability analysis on the slope,curve radius of slope top should be defined to confirm whether the slope can be simplified into a two-dimensional model.
