The contact element model is introduced to simulate the pile-soil’ s reciprocity
then the paper derived the contact element stiffness matrices by adopting parameter variable’s variational principle and parameter variable’s second programming method.With comparison of computing result and test in situation
it shows that the contact element model is suited to simulating the pile-soil’ s shear force transmission and relative displacement.
