Analytical Solution of Displacement and Stress in CRCP under Thermal Load
Due to the relatively longer length of Continuously Reinforced Concrete Pavement (CRCP), CRCP can be regarded as a long slab on the elastic foundation. According to the slippage assumption of shearing stress and maximum principal stress theory, the analytical solutions of the displacement, tensile stress, and shearing stress in CRCP under thermal load are deduced in this study. The following results are acquired from the analysis. Maximum thermal displacement, thermal tensile stress, and shearing stress have relations with the temperature difference, resistance coefficient of friction between slab and base, the thickness, modulus and length of slab. And they are in proportion to temperature difference. The influence of resistance coefficient of friction is significant to maximum thermal displacement and stress. In conclusion, reducing the resistance coefficient of friction is a preferential choice to decrease the maximum thermal displacement and maximum thermal stress.
