摘要
三峡地下电站引水隧洞上弯段属高速高压水流区,衬砌混凝土质量要求高,空间结构特殊,施工难度大。通过对提出的4种混凝土衬砌施工方案的对比和采用专家评分法的评价,定性与定量相结合地分析了施工方案的合理程度,确定了较优的施工方案,并在实际工程中进行了应用。
The flow in upper bend segment of Three Gorges Underground Power Station diversion tunnel is fast,so the requirement on lining concrete of tunnel is strict.As the special structure,it is difficult to construct.Four lining construction schemes are compared using expert assessment method with qualitative and quantitative analysis.By the result,the construction scheme is determined and applied in actual construction.
