摘要

本文介绍了二滩水电站工程导流隧洞右岸0+679剖面二维非线性有限元分析结果。着重研究岩性变化对隧洞稳定性的影响和分步开挖喷锚加固作用

并就施工方面提出了一些建议。本文对右岸导流隧洞的初步设计和施工设计有所裨益。

Abstract

The two-dimensional nonlinear FEM results for Ertan project were introduced in this paper

which were analyses on the section 0+679m of the diversion tunnel on the right bank. The influence of the variation of rock properties on the stability of the tunnel and the role of step-by-step excavation and shotcrete and rock bolting were emphasized here. Some suggestions on construction were given. The paper is useful to the preliminary designs and construction for the diversion tunnel on the right bank.
