Thermal Stress Analysis of Large Scale U-Shaped Aqueduct

Abstract

The aqueduct is one of large scale water conservancy project across river, which is the first level of anti-cracking structure with rigorous control of cracks. At present, the thermal analysis of aqueduct structure most borrows ideas from box-girder bridge structure without considering their difference. As the thermal stress of large-scale concrete structure during construction and operational process is redoubtable, the U-shaped model of a practical aqueduct of South-to-North Water Diversion is established to do the steady and transient thermal analyses. The result shows that the structure of U-shaped aqueduct is reasonable, it is not necessary to take special measures to control the temperature during the construction and operational process.
