【摘要】 为了研究边坡力学系统变形的稳定性,通过对岩质边坡流变机制的分析,以岩石蠕变模型理论为基础,对模型基本元件的参数取值范围进行改变,及引进一种非牛顿黏滞体模型,建立一种能够反映岩石加速蠕变的模型,并在此基础上,提出了一种组合模型:H-K-VP-(H‖—N‖St.V)(其中,—N为非牛顿黏滞体模型),该模型较好地反映了岩石的蠕变性态,并对模型的稳定性及水对边坡稳定性的影响进行了分析。更多还原

【Abstract】 Based on creep model theory of rock,rheology deformation mechanism of rock slope is analyzed and value range of parameter of basic element in model is changed for the purpose of researching the stability of mechanical system of rock slope.A non-ideal adhesion model is introduced so that an acceleration creep model is established.On the basis of this model,a combined model is put forward:H-K-VP-(H‖N—‖St.V),where N is a non-ideal Newton’s model.This model can embody various characteristics of rock creep.The stability of model and the influence of water on it are analyzed.更多还原
