| 摘 要： | 介绍了一种新的计算边坡稳定性的三维极限平衡方法,基于一些边坡向下滑动的运动现象,提出忽略条柱左右侧面竖直向剪切力和前后侧面水平向剪切力的假定。条柱底的剪切力方向不再假定平行于主滑面,而是与主滑面成一定的夹角,通过对考题计算并与其它方法比较,说明了文中方法的可行性。

| Abstract: | A new approach to three-dimensional slope stability analysis is introduced.Based on the fact of slopes sliding downward,the vertical shear stress in the left and right plane of the column and the horizontal shear stress in the front and back plane are assumed to be zero.The direction of the shear stress at the bottom of the column is assumed to have a certain angle with the main sliding direction,but not to be parallel to the main sliding direction.By comparing with other methods,it shows good result. |
