公伯峡水电站有压段衬砌混凝土的设计与施工

Design and construction of the lined concrete in the pressured section of left-bank flood-releasing tunnel for Gongboxia Hydropower Station

全段面钢模台车进行圆形隧洞混凝土衬砌的施工方法首次在公伯峡水电站中应用。公伯峡水电站左岸泄洪洞为有压隧洞,采用全段面钢模台车施工,简要介绍了左岸泄洪洞圆形压力隧洞混凝土衬砌的设计与施工情况,保证了洞衬混凝土的质量,但仍存在一些问题需改进。

The flood releasing turned in the left bank of Gongboxia Hydropower station is a pressure tunnel. It will introduce the design and the condition of construction of circular concrete lined tunnel. In the water power project of upstream of the Yellow River, it is the first that adopting the construction method which conducting circular concreter lined tuned by full face jack plane, and it can gain the fine benefits. But it also needs improve some defects.
