摘　　要：结合西藏水利工程的运行状态,分析了该地区的气候特征及其对混凝土性能的影响。与我国其他地区相比,西藏的年平均辐射量非常高,日温差大,气候干燥、少雨、多大风。混凝土材料的耐久性设计应根据环境条件进行分类设计,但目前国内尚无完整的关于高寒地区混凝土耐久性技术的研究资料,急需开展相关研究。According to the conditions of hydraulic engineering in Tibet, the climatic characteristics of Tibet and its influence on performances of concrete are analyzed herein. Comparing with other regions in China, Tibet has higher annual average solar radiation energy, greater daily temperature difference, more dryness, less rainfall and more gales. The durability design of concrete should be conducted based on the environment, but the complete research data on concrete durability in high and cold regions cannot be obtained at present, so these should be studied immediately.

关 键 词：气候特征 混凝土 耐久性 西藏地区
