第三讲圆弧型滑动面的垂直条块法一、解析法圆弧法为本世纪20年代由费连纽斯(Fellenius)首创,至今在土质边坡稳定性分析计算中仍广泛应用。 (一) 圆弧法的实质费连纽斯视滑体为一刚性块,滑动面为绕某圆心O点并以R为半径所划出的圆弧(如图22)。
The third lecture is the vertical bar method of circular sliding surface. The analytical method circular method was initiated by Fellenius in the 1920s. It is still widely used in the stability analysis of soil slopes. (A) The essence of the circular arc method Farenius views the sliding body as a rigid block, and the sliding surface is an arc drawn around a center O point and radius R (see Figure 22).
