摘要：

建(构)筑物受荷载与环境的共同作用。针对海洋大气环境、除冰盐环境，从材料学角度对混凝土碳化和氯离子侵蚀的相互影响、疲劳荷载与混凝土碳化或氯离子侵蚀复合作用下结构混凝土的损伤劣化进行了总结与分析。重点论述了混凝土碳化对氯离子侵蚀的影响，以及疲劳荷载作用后(下)混凝土的氯离子侵蚀性能，并指出了下一步亟需研究和探索的问题。

The real construction is subjected to the coupling action of mechanical loads and environmental actions. In the ocean atmosphere environment and deicing salt environment, the damage and deterioration laws of structure concrete under the coupling action of fatigue load and carbonation and chlorides as well as the interaction between concrete carbonation and chloride ion penetration were summarized from the viewpoint of material. The effect of concrete carbonation on the chloride ion penetration and the chloride ion penetration behavior after or under fatigue load were discussed emphatically. The existing problems which should be further investigated are suggested.
