摘　　要：强紫外线辐射会加速材料老化,对水工混凝土的耐久性具有不利影响。目前的混凝土耐久性研究多集中于沥青和复合材料的性能方面,对混凝土性能的影响研究较少,且缺乏紫外线辐射的复合侵蚀研究。建议模拟强紫外线辐射对混凝土材料的影响,建立与冻融循环、硫酸盐侵蚀等条件相结合的混凝土服役寿命预测模型。Ultraviolet radiation can accelerate the aging of material and bring a negative impact on the durability of hydraulic concrete. The current researches on durability of concrete mostly focus on its adverse effect on pitch and composite material but hardly on concrete, and lack of the study of concrete under complex attack conditions with ultraviolet radiation. The impact of strong uhraviolet radiation on concrete material is recommended to simulate, and the service life prediction model of concrete under certain attack conditions combined with freeze-thaw cycle and sulfate attack is also proposed to establish.
