摘　　要：采用三维断裂有限元及三维K判据分析了小湾高拱坝底缝扩展的稳定性。结果表明,该缝基本稳定,但中间坝段的底缝深度需作调整,以提高安全度。In this paper, the method of three dimensions fracture finite element and three dimensions K criterion are used in analyzing the stability of base joint of Xiao-Wan high arch dam. It is found that the base joint is stable basically, while the base joint＇s depth of some dam bodies in the middle sections needs some adjustments to improve their safety factor.

关 键 词：高拱坝 底缝 断裂有限元 K判据 应力强度因子
