Based on a project of "Study on Bearing Capacity and Design Method for Curved PC Box Girder Bridge"(number: 03-01K), which came from the Communications Department of Shaanxi Province, temperature gradient effect of curved concrete box girder was researched. Using Finite Element Method (FEM), the effect of temperature gradient stipulated in several codes (Britain bridge standard, Australia bridge specification, New Zealand bridge standard, Japan bridge standard, America bridge specification and China bridge code) were analyzed and compared with. The results show that the calculated stress caused by temperature gradient is relatively unfavorable according to the bridge specification of China, which indicated that it is safer to adhere to Chinese code.
