摘要：

Time dependency of chloride transport has been studied and an improving chloride penetration model has been established. Based on reliability theory, a durability analysis model has been build up and sensitivity analysis of steel corrosion probability has been performed. The analytical results show that age factor, cover depth and diffusion coefficient are key influence factors for corrosion probability of steel bar. Furthermore, influences on corrosion probability of temperature and relative humidity are significant quietly and must be considered in practical engineering.
