摘要
山区不稳定土坡失稳是一种较为常见的地质灾害,如何避免滑坡造成重大人员伤亡及财产损失成为重要的工作。该文通过分析土坡的变形破坏特征和稳定性影响因素,研究斜坡的变形破坏模式;根据定性分析和定量计算,评价潜在不稳定斜坡体的稳定性,比较不同治理方案的优缺点,最终提出预防潜在不稳定斜坡体破坏的防治措施,为类似工程提供了一些经验依据。
Mountain unstable soil slopes are a kind of common geological disasters,and how to avoid landslides caused heavy casualties and property losses becomes an important job.In this paper,through the analysis of soil slopes deformation damage characteristics and stability,the slope deformation and failure mode is studied;based on qualitative analysis and quantitative calculation,the stability of potentially unstable slopes body is evaluated,the advantages and disadvantages of different treatment programs are compared,finally the prevent control measures of potential unstable slopes body damage are proposed,and it provides some empirical evidence for similar projects.
