As the south-north water transfer project starts work, construction of aqueduct in China has entered a new period of development. Static analysis of aqueduct structure is the foundation of design and construction, includes the calculation and analysis of stress and strain of aqueduct structure. The stress and strain of aqueduct structure not only are the index of aqueduct structure rigidity, but also are the basis of identifying whether the aqueduct structural damage occur. According to the

... s of the actual project, this paper uses large-scale finite element analysis software ANSYS to establish three-dimensional finite element calculation model of aqueduct, and analys and explain results, and research the changing rule of the stress and strain of aqueduct in different cases. Research results shows that the degisn of aqueduct is economic and reasonable, can satisfy the strength requirement, its structure is safe and reliable, and can provides certain theoretical basis for design and construction of reinforced concrete aqueduct.
