苏拉马都跨海大桥为双塔双索面的跨海斜拉桥,P46号、P47号为主塔墩,主墩承台采用棱形钢筋混凝土结构,混凝土设计方量为10 632 m3。施工时采用降低混凝土的入模温度、冷却管分层布设、蓄水保温等方法,取得了良好的效果。重点介绍承台施工过程中混凝土的温度控制措施。 Sumamatu Bridge across the Sea is a double-cable, double-cable cross-deck cable-stayed bridge. P46 and P47 are the main piers. The main pier cap is of prismatic reinforced concrete structure with a designed concrete volume of 10 632 m3. During construction, the mold temperature, the cooling pipe layered layout, water storage and heat preservation methods are adopted to achieve good results. Emphasis will be put on the concrete temperature control during the construction of cap.
