The Finite Element Analysis of en Zi Tan Aqueduct in Operation Period

Abstract

As the water resources distribution in China is extremely uneven, inter-basin water transfer project has become an important part of China's water conservancy construction. As part of the the major hydraulic structure in water delivery network across rivers and transportation routes, the design and analysis on aqueduct is important. En Zi Tan Aqueduct is located in Shimen County of Hunan in China. Main content of this paper is about the finite element analysis of the aqueduct on operation period. En Zi Tan Aqueduct is designed flow is of 5.0m 3 /s, longitudinal slope of 1/650, a total length of 1001m. The aqueduct is simple supported beam type, main body is reinforced concrete structure, the cross section is U-shaped and groove in each section length 13m. Top of the tank unilateral laying the bridge deck and railings in order to facilitate pedestrians. The study is using general finite element software to analize, stress and deformation changes on aqueduct body in the operation process; the water load and the earthquake influence on stress and deformation of aqueduct.

Numerical Study on Temperature Distribution of Steel Truss Aqueducts under Solar Radiation

“…An aqueduct has complex temperature boundary conditions. Different from common bridges, an aqueduct [14][15][16] has water flowing through. The temperature boundary conditions of an aqueduct are that the external surfaces contact the surrounding atmosphere and the internal surfaces directly contact the flowing water [9], which induce continuous heat exchange for the external surfaces with the atmosphere through radiation, convection, and conduction and stable temperature for the inner surfaces, respectively.…”
