Finite Element Calculation of Reinforced Concrete Rib Arch Aqueduct

Abstract

Abstract-Guanping aqueduct is located at main canal of reservoir's irrigation district in the Dayong county, Hunan province, this aqueduct is reinforced concrete rib arch aqueduct, main arch ring is variable cross-section reinforced concrete double rib structure, arch axis is suspension of attachment, reinforced concrete bent supports double cantilever u shaped aqueduct, aqueduct adopts reinforced concrete rib arch structure. Static analysis of aqueduct structure is the foundation of design and construction of aqueduct structure, through static analysis of aqueduct structure, we can get the change law of stress and displacement of the aqueduct structure. The aqueduct structure is thin-walled concrete structure, structural analysis is of great significance to study the safety the aqueduct structure. This paper uses universal finite element software to simulate and analyse Guanping reinforced concrete rib arch aqueduct, and gives stress and deformation distribution of aqueduct during construction and operation period, and researches rationality of aqueduct structure design scheme. Analysis results show that Guanping reinforced concrete rib arch aqueduct structure is reasonable, stressing definite, can meet design requirements.
