摘　　要：某水电站碾压混凝土双曲薄拱坝最大坝高111.0m,厚高比仅0.158,且地形不对称,拱坝体形设计难度较大,应力控制标准较高。基于本工程特点,对拱坝体形进行了优化设计,通过精心施工,大坝已安全运行10余年,各项观测数据稳定,工作性态良好,取得了较好的效果。Due to the specific characteristics of a roller compacted concrete double-curved thin arch dam,such as the maximum dam height of 111.0 m,the small thickness-height ratio of only 0.158,and the asymmetric topography,its shape design is of great difficulty and the stress control standard is also high.Considering these characteristics,optimization design of the dam shape is carried out.The dam has operated safely for more than 10 years with stable observation data and good working performance,indicating that the optimization design of the dam shape is satisfactory.
