摘　　要：近些年来,岩质边坡的变形失稳问题一直备受岩土工作者的关注。通过对岩质边坡在一定地质环境条件下的本构问题研究,利用变形的有限性分析判断边坡是否稳定。结合多目标权重分析模型综合分析边坡失稳的影响因素,通过正交实验推断出各影响因素对边坡变形速率的作用程度,进而对不同边坡进行稳定性评价。通过定性分析与定量分析的结合,并用岩石破坏准则加以判断,对滑坡的区域危险性进行预测,从而得出岩质边坡失稳的危险等级。The problem of deformation instability about rock slope has been the concern of ground workers in recent years,Through the constitutive research about the rock slope in a certain geological conditions,the judgement of slope stability has been made in use of the analysis of deformation.Based on multi-objective analysis model comprehensive analysis of the impact of slope instability.we can infer from the impact of factors on the role of slope deformation rate level through orthogonal experiments as well as the different slope stability assessment.We also can get rock slope instability of the danger rate through the combined of qualitative analysis and quantitative analysis along with the determine criteria on rocks.
