摘　　要：根据坝踵处埋设的裂缝计实测裂缝开度和混凝土温度资料 ,对石门拱坝坝踵裂缝开度状况进行了分析 ,得出其深度不超过 5m,且裂缝已稳定的结论。The dam heel crack of the Shimen arch dam is analyzed according to the observed data of dam heel crack opening and concrete temperature. The result shows that the depth of the dam heel crack is not longer than 5 m, and it is stable. The effect of the dam heel crack on the dam foundation uplift is also discussed.

关 键 词：坝踵裂缝 开度 扬压水位 拱坝
