Aiming at some insufficiencies of traditional time effect model of earth rock dam's deformation, considering that time effect model should possess mechanical basis, some convergent non linear time effect models are put forward based upon the theory of soil consolidation.

针对传统的土石坝变形时效模型的一些不足之处，考虑时效模型应该具有力学依据，根据土的固结理论，提出了收敛的非线性时效模型。
