摘　　要：混凝土坝工程投资大、建设周期长,同时存在混凝土容易开裂,影响工程安全的问题.为解决这些矛盾,分析了混凝土施工中浇筑层厚和间歇期的影响因素,介绍了厚层短歇的快速浇筑思路,提出由此产生的不利方面可用适当的温控措施予以解决.该方法在国内几个工程中实施获得成功,实现的效益显著.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.
