Abstract:
The temperature difference and thermal stress of a box aqueduct under the solar radiation was simulated using the finite element software ANSYS. The results indicated that the considerable thermal stresses occur along the longitudinal and transverse directions of the inter-surface of the concrete box aqueduct, and the average value of the thermal stresses exceeds the design tensile strength of concrete. Therefore, the thermal stress generated by the solar radiation should be considered in the design of body structure of box aqueduct, and temperature reinforcement needs to be configured during the design process.
