摘　　要：大藤峡水利枢纽工程通航建筑物布置于黔江左岸,由上游引航道、船闸和下游引航道组成,船闸紧靠主坝,下游引航道内边坡位于船闸下游桩号航下0+359 m~航下2+074 m内。文中对施工期下游引航道内边坡进行综合分析,指出了边坡的主要工程地质问题,并针对边坡稳定进行了评价,由于边坡已采取了防护措施,通过计算和分析,认为边坡整体是稳定的。The navigable buildings of Datengxia Wter Conservancy Project are arranged on the left bank of Qianjiang River,the ship lock is close to the main dam,and the slope in the downstream approach channel is located within 0+359 m~2+074 m under the navigation of pile number of the downstream of the lock.In this paper,the slope in the downstream approach channel during the construction period is comprehensively analyzed,the main engineering geological problems of the slope are pointed out,and the stability of the slope is evaluated.Because the slope has taken protective measures,the slope is considered to be stable as a whole through calculation and analysis.
