采用有限元强度折减法进行边坡稳定分析，建立边坡内最大水平方向位移与折减系数尖点突变模型，并以此作为边坡是否失稳的判断标准。
A cusp catastrophe model of key points horizontal displacement and reduction coefficient is built by using the strength reduction finite element method to evaluate the slope stability.
当你作两个数的减法时，你用一个被减数去减另一个减数。
When you subtract two Numbers, you subtract a subtrahend from a minuend.
当你作两个数的减法时，你用一个被减数去减另一个减数。
In a subtraction operation, the number or quantity subtracted from the minuend.
目前用于边坡稳定性分析的数值方法中的强度折减法通常是仅对强度参数进行折减，且采用的是理想弹塑性模型。
At present, only the strength parameters are reduced when the strength reduction method is used to analyze the slope stability; moreover, the ideal elastoplastic model is used.
因此，采用强度折减法对非均质边坡进行稳定性分析时，建议对整个模型都进行折减。
It is advised that the global strength method should be better than the local strength method when the inhomogeneous slope is analyzed.
