This paper deals the improvement of Gauss precise integration method and its application in train-bridge system.First,with the assumption that the displacement of any moment can be determined by the motion of its two adjacent time steps with the help of Hermite interpolating function,a modified Gauss precise integration method is constructed to solve the structural nonlinear problems,in which the Duhamel term of state equation of precise time-integration method is expanded in terms of 3-node Gauss integration method and the loads corresponding to different integral points are calculated according to interpolation results.
