摘要

根据岩石粘聚力在流变中的作用提出了新的流变机理，建立了新的一维粘弹塑性本构模型，推导了相应的一维蠕变本构关系和相应的一维松弛本构关系，并对蠕变实验结果进行了模拟，结果表明该模型能够反映岩石流变的全过程和模拟岩石蠕变中的第三蠕变，可以避免建模中的模型识别过程，反映岩石流变的机理，物理意义明确，适用范围广。实验证明该模型是合理的。

Abstract

A new rheology mechanism in according with the function of cohesion during the course of rheology for rock is expounded; a new 1-D constitutive model for viscoelastoplastic rock is set up

and the corresponding 1-D creep model and the corresponding 1-D laxity model are deduced. The creep model is used to simulate the curve of rock’s creep in the experiment. The model is verified by the experiment.
