| Abstract: | The disadvantages of concrete dam include not only high investment and long construction period, but also common cracking and its bad influence on safety. To solve such incompatible problems, the influence factors of pouring layer thickness and layer interval are analyzed; then the fast pouring idea of thick layer and short interval is introduced; and it is suggested that the shortcoming caused by the way can be overcome by proper temperature control measures. This method has been successfully applied to several domestic projects; and the benefit is remarkable. |
| Keywords: | concrete dam thick layer and short interval fast pouring temperature control |
