摘要: 根据山区公路滑坡体地质构造、地层岩性和水文地质等条件,考虑滑坡岩体在天然状态和饱和状态2种情况 下,运用极限平衡法和Flac法对滑坡体的稳定性进行计算和分析,提出以预应力锚索框架梁和压力灌浆为主、结合 岸坡防护等辅助措施的治理方案,并用Flac法对滑坡稳定性进行计算与分析,验证工程治理措施的加固效果,保证 滑坡体的稳定.

Abstract: According to the geologic structure,formation lithology and the hydrogeology of the mountainous area highway land— slide,the eale~ation and analysis for the stability of the landslide were perform ed under the consideration of two kinds of wa— ter content with slope limit equilibrium analysis and Flac technique,The main suppo~structure of the landslide—prestressed cable anchor Lame beam and the pressure grouting were put forward as well 8.8 additional engineering measures for bank slope protection.Th e Flac technique was applied to the analysis and validation on landslide stability after comprehensive treatment. Th e landslide—treatment pro/ect is able to guarantee the stability of landslide.

Key words: mountainous area highway, landslide, stability, Flac
