摘要
钢筋混凝土结构是目前应用最为广泛的土木工程结构,其在服役过程中容易受到各种因素影响而发生多种病害,从而提前退出使用。研究各种病害对钢筋混凝土结构的影响对于确保钢筋混凝土结构的安全有着重要意义。本文采用拟人的方法将钢筋混凝土结构所受的各种病害(包括:钢筋锈蚀、混凝土碳化、化学侵蚀、冻融破坏、碱集料反应、疲劳破坏、开裂等)归结为几种病症,以此来分析各种病害导致钢筋混凝土的劣化机理,为减轻混凝土病害的影响,确保钢筋混凝土结构的健康提供帮助。
Reinforced concrete structure,most widely used in civil engineering,is affected by so many diseases during its service life that it reaches to failure ahead.Research on influence of disease on concrete structure is of significance for ensuring the safety of reinforced concrete structure.In this paper,the diseases happened on concrete structure,including of reinforcement corrosion,concrete carbonation,chemical corrosion,freeze-thaw destruction,alkali-aggregate reaction,fatigue and so on,are analyzed and defined as diseases in human,which is used to analyze the deterioration mechanism of reinforce concrete due to these diseases.The analysis could reduce the effect of disease and help to keep reinforced concrete structure healthy.
