探讨较优的土石坝变形时效模型

Probe into relatively better time-effect model of earth-rock dam's deformation

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。通过比较各模型时效分量的计算值与实测值 。

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. Through comparion between measured and calculated time effect components for various models,it shows that the ameliorated time effect models of earth rock dam's deformation are more reasonable than the traditional one.
