Numerical Simulation Methods and Parameters of Geo-Grid Rein-Forced Retain Fly Ash Wall

Abstract

Deformation of the geo-grid rein-forced retain fly ash wall and the reinforcing effect of geogrid reinforcement, depends largely on the role of interface properties between the geogrid and fly ash. Interface in the numerical simulation of the mechanical properties of the main elements reflected in the geogrid on the constitutive parameters,for example, shear stiffness,Cohesion,Modulus, reinforcement length and so on. In this paper, geogrid reinforced fly tangential stiffness, cohesion, elastic modulus, reinforcement length and other parameters on geogrid reinforced retaining wall deformation characteristics of fly ash for numerical simulation and comparative analysis,Obtained parameters on geogrid reinforced retaining wall mechanical behavior of fly ash, stability and reinforced the effect of law, Provide theoretical and analytical basis for the geogrid reinforced and reinforced fly ash characteristics of the interface wall wide application in engineering.
