摘要
水工混凝土结构主要存在冻融、裂缝、溶融、碳化和碱集料反应引发的老化问题。上述各种单一病害因素作用下混凝土的老化问题,可以评价混凝土在单一因素作用下的老化问题,多种因素共同作用时,对混凝土的损伤并不是各单一因素作用的简单叠加,探讨了各种单一因素作用下和各种因素共同作用下的混凝土的病害破坏机理。
The degradation caused by the reaction of freeze-thaw,cracks,carbonization and alkali-aggregate often responses on hydraulic concrete structures.The degradation of concrete caused by the previous single damage can be used to analyze the degradation of concrete caused by one damage.Multi-damage interaction responses on concrete is not the superposition of all the single factors.The paper discussed the destruction mechanism caused by the single damage and all damages interaction.
