摘　　要：针对坝工界十分关注的拱坝上滑失稳问题,利用两个200 m高的拱坝模型,分析其建基面上的剪力,结果表明:高的双曲拱坝上滑失稳的可能性较小,而高的单曲拱坝却存在上滑失稳的可能,设计时应进行验算。Aiming at stability against up-sliding about which the dam engineers have concerned closely,this paper analyzes shear of contact face by use of two 200 m high arch dam models.The results show that there is little probability of stability against up-sliding at high double curvature arch dam,but there is possibility against up-sliding at high single curvature arch dam.Thus,we should study the stability against up-sliding for design.

关 键 词：双曲高拱坝 单曲高拱坝 上滑失稳 建基面 剪力
