中文摘要：

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.

英文摘要：

High arch dams bring some new problems because of the high height,long base width and the big silo.This article analyzes some common troubles about the construction of high concrete arch dams,such as： long base width and large constraint face;difficulty of processing and analysing large amount of field data;the stronger constraint from the foundation and concrete constraints,and proposes the following measures：1） selecting the appropriate semi-mature age of concrete;2） using dynamic motion control in space-time during the construction period,establishing the decision support system of temperature control;3） reasonably planning water cooling including arranging medium-term cooling and properly planning secondary cooling.
