 Optimum design and analysis of U-shape thin-wall aqueduct based on genetic algorithmWen-Liang Ma and Rui Yuan International Journal of Industrial and Systems Engineering, 2021, vol. 38, issue 1, 1-18 Abstract: In order to save project investment and reduce project quantity, the optimal design of aqueduct is the main problem in the project therefore, carrying out the optimal design and simulation analysis of U-shaped thin-walled aqueduct has important engineering application value. The paper takes Sha River aqueduct as the research object and adopts the direct search and point checking method of mixed discrete variable optimisation design. It also adopts the structural optimisation design method based on genetic algorithm and gives the optimal design scheme of U-shaped aqueduct. The optimisation design method has the advantages of fast convergence speed, high convergence efficiency and strong global search ability. The results show that, U-shape aqueduct structure is smooth, it has good mechanical properties, and the structural stress is small and can meet the strength requirement. The maximum vertical displacement of the aqueduct occurs in the middle of the span, the vertical displacement value is small, which can meet the requirement of stiffness. Keywords: aqueduct; optimisation design; discrete variable; finite element method; stress analysis; vertical displacement.
