摘要：
According to the related theory of porous media, taking the effects of concrete internal moisture into account, the mechanism of the concrete creep was researched. The numerical computation formulas of the finite element have been given. The correponding computation procedure of the numerical simulation has been developed. Combined with single axis compresses test of the concrete, the analysis of concrete creep was implemented. The result of numerical simulation shows rationality of the theory and exactness of the procedure in this paper.
