| Abstract: | Galerkin method is adopted to set up a equilibrium equation for global side-torsion stability analysis of a U-shaped and rectangle thin-shell aqueduct,and a calculation formula for critical load is deduced. The validity of the formula is proved through calculating examples,the characteristics of the side-torsion stability of the aqueduct is discussed,to provide references for the design of a large-scale thin-shell aqueduct. |
