THERMAL COUPLING EFFECT ANALYSIS OF GEOTECHNICAL ENGINEERING REINFORCEMENT MATERIALS BASED ON FINITE ELEMENT ANALYSIS

ABSTRACT
In the analysis of material thermal coupling effect, the stress-strain relationship of material is seldom considered, which leads to the greater influence of material grid strain effect, which leads to the poor accuracy of material thermal coupling effect analysis. Based on this, this paper puts forward the thermal coupling effect analysis of geotechnical engineering reinforcement materials based on the finite element analysis. According to the concept of cooling zone, the thermal resistance value of the material is calculated. Combined with the stress relationship and thermal resistance value, the thermal coupling effect of the material is analyzed by finite element discretization. In the experiment, the geotechnical engineering reinforcement material is used as the analysis object to analyze the material thermal coupling effect. The result of the proposed method is closer to the actual situation than that of the traditional method. The accuracy rate of the material thermal coupling effect analysis is up to 98%, which proves that the proposed method is feasible.
