Based on general software MARC, a user subroutine CRPLAW used for single crystal creep analysis has been developed.

In the paper, the finite element method regarding the effects of wetting and creep analysis of asphalt concrete core are studied.

Furthermore, a function of hyperbola combined power is adopted in modeling the curves of long-term triaxial creep test of the asphalt concrete; and creep analysis is performed for the dam.
