摘　　要：小湾拱坝高２９２ｍ，坝址河谷宽、岸坡相对较平缓，拱圈又比较扁平，应进行沿建基面的抗滑稳定复核计算。本文介绍了复核计算的基本概念及算式，并列举了计算成果。Xiaowan Arch Dam will be 292 m in beight. The river bed is wide at the damsite. Otherwise, bank slopes are relatively mild and the arch ring is rather flat. Therefore, a re-check calculation of stability against sliding along the foundation base is carried out. This paper deals with the basic conception and formulae in the re-check calculation, and the results of this calculation are cited as well.
