高拱坝由于坝体较高,底宽及仓面都较大,会带来一些新的问题.介绍分析了一些高拱坝建设中常见的问题:底宽长,约束区范围大;现场数据量大,给处理分析带来困难;受到地基和混凝土的约束更强等.提出了以下几点措施:1)选择合适的混凝土半熟龄期;2)施工期进行时空动态控制,针对具体工程建立温控决策支持系统;3)合理规划通水冷却,安排中期冷却以及适当地规划二期冷却.
Due to the high dam height, bottom width and warehouse surface, the high arch dam will bring some new problems.This paper analyzes and analyzes some common problems in the construction of high arch dam: wide bottom and wide confinement area; Large amount, difficult to process analysis, more restricted by foundation and concrete, etc. The following measures are proposed: 1) Selection of suitable semi-mature concrete age; 2) Space-time dynamic control during construction period, for specific project establishment Temperature control decision support system; 3) Rational planning of water cooling, mid-term cooling arrangements and proper planning of the second phase of cooling.
