Abstract：Based on research results of transverse temperature gradient effect for bridges, referring to the temperature gradient of Chinese General Code (JTG D60—2004), bridge location and trend, three twodimensional temperature gradient models were constructed. Using finite element software ANSYS, the forces and the deformations of a curved girder bridge were investigated under code temperature gradient and 2D temperature gradient, respectively. The comparison of calculation results show that the overall beam body is shifted outward or inward under the four kinds of temperature gradient mode, and the radial displacement of beam is the largest under twodimensional temperature gradient Ⅱ. Based on the characteristics of 2D temperature gradient effect and code temperature gradient effect, the design suggestions of full torsion resistance supports for curved continuous girder bridges are proposed that midpier is designed with fixed support. The side pier is designed with radial limit support, and the rest piers are designed with twoway activitive support. The proposed design can limit the action of radial displacement of beam body under twodimensional temperature gradientⅡ, and the bearing radial force distribution is reasonable.
