溪洛渡双曲拱坝二期冷却效果研究

Study on Second-stage Cooling Effect of Xiluodu Double Curvature Arch Dam

溪洛渡双曲拱坝是拟建的世界上最高的混凝土拱坝之一,施工期跨越5个高温季节,温控措施要求严格。本文利用数值仿真计算方法,研究了溪洛渡二期冷却效果,特别是研究了二期冷却时间对冷却效果的影响。研究表明,二期冷却对混凝土降温效果显著。

Xiluodu Double Curvature Arch Dam is one of the highest concrete arch dams to be constructed in the world.The construction period would cover 5 hot seasons and strict temperature control measures shall be taken for the dam concrete.In this paper digital simulation calculated is used to study the secondstage cooling effect of the dam body,especially the impact of secondstage time on the cool effect.The study indicates that the secondstage cooling would achieve good results in lowering the concrete temperature.
