| 摘 要： | 对小湾拱坝底部设诱导缝进行了模拟,应用三维有限元方法对小湾拱坝底部设诱导缝和不设诱导缝的拱坝坝体的应力变形进行了计算分析.结果表明：设置诱导缝,能有效地改善坝踵附近的应力分布,且对拱坝的整体稳定安全度影响很小.

| Abstract: | The inducing joint built at the heel of Xiaowan arch dam is simulated by contact element; and the stress and deformation of Xiaowan dam, under the condition of having inducing joint or not, are computed by 3-D FEM. The result shows that with the help of inducing joint, the stress distribution nearby the dam heel is evidently improved while the integral stability factor of Xiaowan dam is slightly influenced. |
