将混凝土在服役期间可能经受的有害因素归纳为化学、物理、力学三大类，接着对此三类单因素条件下的损伤及其破坏机理进行了描述。根据实际工程多因素同时作用的情况，将组合为化学和力学、物理和力学的二元叠加。结合国内外的大量文献资料，对组合中可能出现的双因素复合的机理进行深入的阐述，最后对多元复合的情况进行了描述，揭示了不同因素耦合的损伤叠加正负效应和交互作用。

Three factors influence the durability of concrete life including chemical, physical and mechanical are indentified. The paper describes that the damage mechanism of concrete under these three factors is described. According to the practical engineering, the two-variable-added, the chemical factors and mechanical factors, the physical factors and mechanical factors are combined. On the basis of the recent references, the composition and the muhi-e｜ement composition mechanism are discussed. The damage superposition, positive and negative effects and interaction between different factors are announced.
