摘　　要：在对四川三台罗家大石包滑坡区的工程地质条件、滑坡特征、滑坡成因等分析的基础上,对其边坡稳定性进行了定性分析和定量计算。运用Janbu法计算表明滑坡体已经处于临界平衡状态,在饱水状态下严重破坏失稳,与定性分析和实际情况相吻合。提出了采用设置排水系统、清除危岩体和支挡工程等综合治理措施。Based on the analysis of the engineering geological condition, deformation behaviour and material component of landslide, qualitative analysis and quantitative calculation were carried out. The results obtained from the computation using Janbu method indicate that the landslide has been in the state of critical balance. But it behaves as serious failure instability in the state of saturation. The result corresponds to the qualitative analysis and practical situation. A comprehensive control program was recommended, which combined earth-remaining walls, remove hazardous rock before rainy season and glide-resisting stake.
