| Abstract: | Based on the peculiarity of concrete, the cause of formation of temperature-crack in surface of arch dam are studied and the temperature process and temperature-stress process are analyzed and calculated. With the method of linear rupture mechanics, the stabilization of the surface temperature-crack are studied and some interrelated conclusions are made. |
