| 摘 要： | 假定滑面正应力分布为含2个待定参数的拉格朗日插值函数，推导出含锚固力作用的滑体水平力、垂直力和力矩平衡方程，直接得到满足给定安全系数要求的锚固力系数解析解。这种锚固边坡计算方法克服了传统方法导致滑面正应力突变的缺点，且计算过程极为简便，并成功应用于实际边坡加固工程。

| Abstract: | Based on the assumption that the normal stress distribution over the slip surface is represented by a Lagrangian interpolation function involving two unknowns, the horizontal and vertical forces and moment equilibrium equations for the sliding body are derived incorporating the effect of anchor forces. Then the analytical solutions of anchor force factors are obtained directly, which satisfy the requirement of the specified factor of safety. This new method for the analysis of anchor reinforced slope overcomes the disadvantage of abrupt change in normal stresses on the slip surface which is encountered when using conventional procedures and the computation process is rather straightforward. This method has been successfully applied to slope stabilization engineering. |
