摘要
Abstract
This paper takes the water chamber of the low-bypass import of the Lujiagang reservoir for the study object, using ANSYS software to simulate the diffusion process of Cl- in reinforced concrete structures in the water chamber,and making the service life prediction of concrete structures caused by reinforcement corrosion damage. The simulation results show that using ANSYS software to simulate the process of chloride diffusion in concrete structures can reflect the distribution of unstable concentration field in the concrete structure. Taking the critical chloride concentration in the protective layer depth into consideration, we can predict the service life of the structure and provide a reference for other practical engineering to deal with similar situations.关键词
