Abstract A special finite difference method is applied to solve beams on elastic foundation .A whole beam is divided into several partitions, shear on each of them is consecutive and adapt to Runge-Kutta method. Singularitys between these partitions are disposed by making a transfer matrix base on equilibrium condition of inner force. complex boundaries can be loaded easily and results generated by this method is high accurate since inner forces are unknown quantities. The numerical simulation by this method about the construction procedure of a ditch is presented as well.

Key words： beams on elastic foundation runge-kutta transfer matrix ditch
