| Abstract: | First,the status of monitoring of Gongboxia face rockfill dam is introduced.Then the monitored temperature data are analyzed to find the temperature changing rule of panel and stone.And preliminary conclusion about the relationship between temperature changing and the panel crack is drawn.Last,finite element model is used to calculate temperature stresses.Some suqqestions are proposed such as the effective panel insulation measures should be taken and panel fracture development monitoring should be strengthened. |

| Keywords: | Gongboxia dam crack atmospheric temperature strain gauge |
