谈桥梁承台大体积混凝土的施工技术

Discussion on mass concrete construction technology of bridge cap

探讨了在北方高温差气候条件下,采用优化混凝土配合比设计、冷却管降温及双掺技术等多项措施对承台大体积混凝土进行施工,顺利完成了施工生产的任务,并积累了丰富的复杂地质条件下的现场施工经验。

The paper explores mass concrete cap construction with optimal concrete mixing proportion design, cooling tube cooling and double- mixture technology and so on under high temperature conditions in the north of China, successfully accomplishes construction tasks, and accumu- lates site construction experience under complicated climate conditions.
