岩石高陡边坡的岩体模型及其参数研究

Study on Rock Mass Models and lts Parameters in High and Steep Rocky Slope

岩石边坡稳定性分析，通常将边坡岩体的模型抽象为地质模型、力学模型及几何模型三种。本文提出应根据分析方法的侧重点分别建立相应的模型，即针对三维相似模型试验建立地质概化模型；针对块体稳定分析建立块体一夹层模型；针对数值模拟建立等效连续模型。文中结合三峡链子崖危岩体建立了这三种模型并确定相应的参数。模型试验与计算成果基本一致，与现场实际情况吻合较好。

In the stability analysis of rocky slope,the rock mass is generally abstracted into geologic model,mechan-ical medel or geometric medel.The distinct model must be selected according to the feature of analyzing methodusd,i.e. the general geologic model is established for 3-d model test and the equivalent continuum medel is es-tablished for numeric calculation.Taking the Lianziya precipise as an example,these models with corresponding pa-rameters are made in the paper.It is shown that the results of model test,calculation and field test are consistent with each other.
