摘要
根据宜昌气象站３４年逐日气象观测资料，分析了影响三峡坝区冬季施工的低温条件与冬季施工时段变化规律。分析表明三峡坝区低温日数与冬季施工时段存在着十分明显的年际变化特点与规律，这对大江截流期选择。
Based on 34 years daily meteorological data from Yichang station in Hubei Province,the low temperature condition and winter construction period of Sanxia dam area were analysed.The result shows that the low temperature days and winter construction period in Yichang exhibited very obvious interannual variation.This provides background for winter temperature prediction and preparation for the Sanxia Project.
