岩石流变特性及高边坡稳定性流变分析

RHEOLOGICAL CHARACTERISTICS OF ROCK AND STABILITY RHEOLOGICAL ANALYSIS FOR HIGH SLOPE

叙述了岩石的压缩蠕变试验及方法；将蠕变强度和瞬时强度作了比较；拟合出了蠕变曲线经验公式；得到了蠕变理论模型及其参数；经综合分析和类比确定了蠕变参数。利用开发出的岩质边坡稳定性流变分析微机软件，对三峡船闸边坡进行了模拟边坡开挖过程的粘弹性有限元分析，并计算了船闸运行期边坡岩体的长期变形。

This paper introduces the method and results of compressed creep for granite, and compares the creep strength with the instantaneous strength. The experimental formula of creep curve is fitted. A creep theory model and its parameters are obtained. To model the process of excavation of Three Gorges ship lock slope, the slope stability is analyzed by viscoelastic FE microcomputer program developed by authors. The deformation of the slope rockmass is calculated during lock slope running. The result offers some references for project design and execution.
