摘　　要：为了研究圆拱直墙式廊道圆拱中心角、廊道埋深、衬砌厚度、断面高宽比以及衬砌的混凝土强度等级对抽水蓄能电站库底及库周廊道衬砌配筋的影响,采用边值法计算方法,引用理正岩土程序6.5对抽水蓄能电站库底及库周廊道衬砌内力和配筋进行计算,结果表明全库盆防渗水库库底和库周廊道内、外侧的配筋面积随圆拱中心角、廊道埋深、衬砌厚度、断面高宽比以及衬砌的混凝土强度等级的改变而呈现一定规律的变化,尤其是廊道底板内外侧配筋面积变化较大,该结果可以为抽水蓄能电站全库盆防渗水库库周及库底廊道设计提供参考依据。In order to analyze the influence of the central angle of the circular arch,buried depth of the corridor,lining thickness,section aspect ratio,and concrete strength grade of the lining of the circular arch straight wall corridor on the reinforcement results at the bottom and around the gallery of a pumped storage power station,adopting the boundary value calculation method,applying Lizheng Geotechnical program 6.5 to calculate the internal force and reinforcement of the corridor lining at the bottom and around the Pumped-storage hydroelectricity,the results indicate that the inside and outside reinforcement area at the bottom and around the pumped-storage varies regularly with changes in the central angle of the circular arch,the depth of the gallery,the thickness of the lining,the aspect ratio of the cross-section,and the strength grade of the lining concrete,especially the area of reinforcement on the inner and outer sides of the corridor bottom plate varies greatly,the results can provide a reference for the design of the corridor around and at the bottom of the Pumped-storage hydroelectricity with full basin seepage prevention.
