摘要

紫坪铺水利工程2# 导流洞出口高边坡位于坝址右岸条形山脊下游侧，有F3巨厚断层穿过。边坡在开挖过程中，覆盖层曾发生过多次滑坡，给工程的施工进度和安全性以及人们的生命财产带来了许多安全隐患。为此采用了多种加固方法综合治理了该边坡。以FLAC3D为手段，模拟了边坡的开挖支护过程，并分析了所施加的预应力锚索、抗滑桩等支护结构对边坡稳定性的改善情况。计算结果表明，所采取的加固措施有效地遏止了边坡变形，边坡整体趋于稳定状态。

Abstract

The outlet of the diversion tunnel #2 of Zipingpu Hydraulic Project is located on downriver side of the right bank chine. It is under the trough valley formed by the huge fault zone. It happened several times that the overburden layer of the slope slide during the construction. The safety of people lived near the project was threatened and the construction progress of the whole project was badly affected. Many kinds of methods were synthetically taken to maintain the stability of the slope. FLAC3D is used to simulate the excavation with the prestressed cables and friction piles. The effect of the support is analyzed from displacement field

stress field and other aspects. The results show that the support can remarkably control the deformation of the slope and the slope was stable after reinforce.
