AB - 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.
