To deal with the problem that position of dowel bar in rigid pavement existed deviation, double-layer pavement structure model considering interlayer contact status was established. The effect deviation of three-dimensional position, such as, horizontal angle, vertical angle and embedded depth on joint load-transfer capacity was analyzed. Prediction model of load-transfer capacity considering dowel bar position deviation was established by ternary nonlinear regression. Load correction factor and its range were proposed too. After verified by FWD testing, this prediction model can reflect joint load transfer capacity well when dowel position was deviation. The effect of dowel bar horizontal angle on joint load-transfer coefficient was little. On the contrary, joint load-transfer coefficient was almost linearly decreased with its vertical angle increase. The coefficient reduced by approximately 12% when vertical angle was 15°. Meanwhile, load-transfer coefficient reached maximum when dowel bar embedded in middle of surface. It would decline either position upwards or downwards. Especially, it would reduce by 10% when the position downwards 2cm.
