| 摘 要： | 西藏某水电站右岸边坡施工开挖前，由于地表植被茂密，基岩出露的部位均为较好的岩石，而覆盖层盖住的部位，往往是较破碎的岩石。前期勘测中，由于时间紧迫，对此经常忽略，为施工开挖可能带来了隐患。文章旨在通过对这一过程的表述，能够引起同行的重视，也供在施工开挖中遇到类似情况参考。

| Abstract: | Before excavation of the right bank slope of a hydropower project in Tibet, the exposed bed rock is sound rock due to surface dense vegetation, but the portion covered by overburden is often of fractured rocks, which is usually neglected at early-stage investiga- tion due to time pressing. This might have brought hidden danger to the later construction excavation. The paper describes the issue and hopes to bring counterparts attention to it and provide reference for similar situations in future excavations. |
