It is proposed that the ideal elastoplastic model can be used to determine the safety factor, and the variable modulus elastoplastic model to calculate the deformation field.

因此，建议采用理想弹塑性模型的强度折减法确定安全系数，采用变模量弹塑性模型强度折减法确定变形场。

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.

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。
