摘　　要：乐昌峡水利枢纽右岸防汛道路受强降雨影响,边坡多次出现塌方,导致原有村道中断、乐昌峡右岸公路通行受阻。对此,在调查并掌握水文地质状况的基础上,提出边坡开挖卸载、边坡局部卸载+支护以及利用隧道改线三种处理方案。经综合比较分析,推荐边坡局部卸载+支护作为实施方案。该设计经验可为类似工程提供参考。Affected by heavy rainfall,the flood control road on the right bank of the Lechang Gorge Hydrojunction has experienced multiple slope collapses,leading to the interruption of the original village road and blockage of traffic on the right bank highway of the Lechang Gorge.In response,based on investigation and understanding of hydrogeological conditions,three treatment plans are proposed,namely,slope excavation and unloading,partial unloading of slopes with support,and utilizing tunnel realignment.After comprehensive comparative analysis,it is recommended to implement the plan of partial unloading of slopes with support.The design experience can serve as a reference for similar projects.
