A Study on the Main Factors Affecting the Reinforcement Corrosion in Mechanically Stabilised Earth Walls and Predict the Service Life of the Wall

In this study, the Principal Component Analysis method is applied to determine the main factors affecting reinforcement corrosion in mechanically stabilised earth (MSE) walls. A response surface model is used to build the correlation function between corrosion and main factors, which is then applied to design a program to predict the service life of the MSE wall constructed using steel reinforcement (MSE-T). The results of MSE-T program are used to simulate the scenarios of steel corrosion of MSE walls by FLAC software, which could show the stress-strain displacement of the walls at the extracted time. The research results could provide a warning of degradation of the MSE wall in the end stage of working period to enhance safety in the operating process and propose the solutions to improve the longevity of the walls.
