| Abstract: | At first,influential factors of temperature boundary conditions have been comprehensively analyzed;and formulas for calculating influential factors have been given accurately.Then based on the transient analysis type of FEM,a method of calculating transient temperature field of concrete aqueducts during operation period has been given.The computing results of experimental concrete trough are compared with the experimental ones;and it is shown that the formulas and method proposed are accurate.Finally,some useful conclusions are drawn by calculating the temperature field of Minghe River Aqueduct for the South-to-North Water Transfer Project.The research results can offer reference for the construction of aqueducts for the South-to-North Water Transfer Project. |
