Three-dimensional Finite Element Analysis on the Rectangle Concrete Aqueduct with Sidewalk

The rectangle concrete aqueduct with sidewalk was analyzed by the finite element analysis software.After the constraint of the rectangle concrete aqueduct with sidewalk when there is crowd load and non-crowd load,its deflection and stress difference were compared.According to the analysis on the features of its strength and stiffness,in order to improve the scientificity,rationality,economic safety and stability of the aqueduct,every part was reinforced respectly.
