(1) When the pouring temperature equaled to the 10-day mean temperature, the maximum temperature of dam was 38.96℃. Because of temperature load was the main load of arch dam, strict temperature control measures should be adopted to reduce the maximum temperature of dam, and so decrease thermal stress of dam. (2) Pouring temperature and material grade were the main factors at the influence on maximum temperature of dam. When material grade was decided, the lower the pouring temperature was, the smaller the maximum temperature of the dam was. Therefore, in strong restraint area, pouring concrete in period of low temperature was better, which was of benefit for temperature control measures. (3) The maximum temperature of the dam appeared in the area of pouring in high temperature season, because the outside temperature and pouring temperature were high, and the heat dissipation condition in dam was poor.
