3-D FEM Analysis of Large-Scale Prestressed Concrete Aqueduct in the Middle Route of South-to-North Water Diversion Project

Article Preview

Abstract:

Taking the properties of aqueduct in the middle line of the South-North Water Diversion Project, such as high flow, long span, large load and cross section and so on, two schemes about layout of prestressed steel strands are put forward. In order to guarantee safety of the project and structural optimization, 3-D FEM is adopted to study the regularity of distribution of stress and strain on control section under each condition of the two schemes. The results show that the design of steel strands in the first scheme (wavy steel strands) is much more reasonable and meets the requirements for anti-crack and deflection of the aqueduct body.
