In order to solve the problem that the solution stability and convergence are influenced by time step selection in solving consolidation equation by typical finite difference method,aiming at the solution of one-dimensional nonlinear hyperbolic consolidation equation with non-constant consolidation coefficient,we put forward a numerical solution with time discretization by precise integration method,derive the solving process of this method in detail,and compare the precise integration solution with the typical finite difference solution combining with engineering example.The results show that the precise integration method is not limited by the time step size,and has good accuracy and numerical stability.
