金水沟特大桥承台大体积混凝土施工技术

通过对金水沟特大桥6#墩左幅承台的温度监控，有效地把混凝土的内外温差控制在了规范规定的范围之内。同时利用混凝土水化热温度场分布图和混凝土各测点在垂直和水平方向上的温度变化曲线，总结出大体积混凝土温度场的基本规律．这为后续的承台施工提供了技术经验，取得了较好的施工效果。

Technique for Large-volume Concrete Construction of Jinshuigou Huge Bridge

Through the temperature supervision on the left bearing foundation of the sixth frusta of Jinshuigou huge bridge, the concrete temperature difference inside and outside was controlled in the range set by criterion. At the same time, the basic rules for temperature field of large-volume concrete was summarized by the heat of hydration distributing curve of concrete and the temperature-time curve of every concrete measured spot. These rules provide the technique experience for later construction of bearing foundation, and can get good construction effect.
