Thermal Stress Analysis of Large Scale U-Shaped Aqueduct

摘要

The aqueduct is one of large scale water conservancy project across fiver,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.
