摘　　要：文章采用水热化估算方法对北方地区冬季水工混凝土施工的热能损耗率进行试验。试验分析表明:冬季水工混凝土热能损耗的主因在于其内壁厚度,热能损耗率可通过增加其内壁厚度来有效降低,从而增强冬季水工混凝土施工结构的稳定程度。研究成果对于北方地区冬季水利工程施工设计具有重要参考价值。The hydrothermal estimation method is used to test the thermal energy loss of winter hydraulic concrete construction in the northern area.The experiment shows:the main reason for the thermal energy loss of hydraulic concrete in winter is its thin wall thickness.The thermal energy loss rate can be effectively reduced by increasing the internal thin wall thickness,thereby enhancing the stability of the hydraulic concrete construction structure in winter.The research results have important reference value for the winter water conservancy project construction design in the northern region.
