Abstract: Affected by the Qinghai-Tibet Plateau tectonic structures and the warm-humid climate during the Last Glacial Epoch,the Jinsha River was incised into deep valley, on which numerous large-scale landslides are distributed and revived under the effects of rainfall and water-level fluctuation. In this study,the Baisheng landslide was studied using field investigation and geo-mechanical analysis for its formation evolution,geo-mechanical model and stable mechanism of rainfall-type water-level fluctuation slopes in deep-incised river valleys. According to the study results,the geological evolution and sliding processes of landslides are divided into six stages,including the initial status,unloading and degradation of rocks,extrusion and plastic flow,instability triggered by rainfalls,disintegration and compaction of deposit,and local resurrection by water-level fluctuation in the front of landslide. The stability of slopes gradually reduces due to unloading of rocks, water softening, and creepage by rainfalls or water fluctuation of reservoir. The slopes are stable when the stability coefficient is 1.12 under the natural condition; while landslides failure when the stability coefficient is 0.98 under heavy rain conditions and fluctuation of reservoir water level.

Key words: Jinsha River, deep-incised valley, genetic evolution, formation mechanism, geomechanical model
