摘　　要：针对宝成铁路部分地段沿嘉陵江右岸前进,荷叶坝水电站的蓄水运行易导致水库塌岸等问题,从边坡地层岩性、地质构造、边坡形态、库水位变化、水库淤积等方面对铁路路基的稳定性进行分析,并对其进行了分段评价,提出了路基边坡的防护措施。A section of Baoji-Chengdu railway lies along the right bank of the Jialing river, and the consequences of some disaster such as the reservoir bank collapse-prone because of water-impoundment and running of Heye dam hydropower station have great negative influence on the railroad. Accordingly, in this paper, the stability of the railway embankment is analyzed from the slope lithology, geological structure, slope morphology, reservoir water level changes, reservoir sedimentation, etc. And then the railway has been segmented evaluated. FinaUy, the subgrade slope protection measures have been put forward.
