Creep analysis of high slope based on viscoelastic-plastic model
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.
