<p>The hydraulic tunnel lining concrete is prone to cracking during construction if no effective temperature control measures are taken. Multiple factors contribute to tunnel cracking, including the properties of concrete materials that have a significant impact on the tunnel lining. It is necessary to study the influence of concrete materials on the thermal stresses of the lining and to propose corresponding measures to prevent cracking. In this paper, the finite element method is employed to calculate the temperature and stress fields of the lining concrete in the diversion tunnel. An analytic hierarchy process is employed to rank the importance of different influencing factors. The concrete mix ratio experiment and field test are carried out based on the theoretical analysis results. The crack control measures and construction suggestions are proposed. The results show that the rise in adiabatic temperature and its rate influence the thermal stress of lining concrete. The linear expansion coefficient demonstrates the most pronounced effect on thermal stress. When autogenous volume deformation exhibits shrinkage behavior, the tensile stress of the lining concrete increases accordingly. The larger the final elastic modulus, the greater the thermal stress. The field test of lining concrete is carried out by combining high sulfate-resistant cement and natural sand, which is beneficial for temperature control and crack prevention. It is recommended to adopt temperature control measures such as using medium-heat cement, adjusting the design age of the concrete mix ratio, and increasing the amount of fly ash.</p>
