| Abstract: |
| Base on the methods used in designing small U-shape aqueducts, the UD40, UD50, UD60 and UD90 aqueduct-type fabricated U-shaped canals were designed with the combination of socket-type in connection structure of canals for the modular design of irrigation canals in China. Then the structure calculation of the aqueduct U-shaped canals was studied and the section designs of UD60 and UD90 were verified respectively by beam theory and finite element analysis. The results showed that, the end structure of aqueduct-type fabricated U-shaped canals was well improved by the socket connection which enhanced the flexural rigidity of joint surface and improved water leakage problem of joints. Under the consideration of component prefabrication, transportation and construction, the requirements of bearing capacity were met. At the same time, with reasonable dimensions of section and span, the aqueduct-type fabricated U-shaped canals could be applied in the terminal irrigation canals by satisfying the necessity of practical engineering. The above study can provide some technical support and reference for the optimization and modular design of irrigation canals. |
