摘　　要：文章基于Burgers蠕变模型与带拉伸截止限的Mohr-Coulomb塑性屈服准则组合而成的复合粘弹塑性模型--Cvisc模型,建立某水库大坝左坝肩高边坡的三维边坡有限差分法分析模型。分析某蠕变体边坡长期蠕变的变形监测资料,并反演分析得到计算模型各岩层蠕变参数,据此研究蠕变体边坡的变形,为边坡的加固处理提供基础资料和参考依据。Based on the combination of Burgers creep model and Mohr-Coulomb plastic yield criterion with tensile cut-off limit,a composite viscoelastic plastic model,the Cvisc model,is established to analyze the three-dimensional finite difference method of a high slope on the left abutment of a reservoir dam.The paper analyzes the deformation monitoring data of a certain creep variant slope for long-term creep,and obtain the creep parameters of each rock layer in the calculation model through inverse analysis.Based on this,the paper study the deformation of the creep variant slope and provide basic data and reference basis for the reinforcement treatment of the slope.
