TÓM TẮT
In this study, a program to forecast the service time of mechanically stabilized earth (MSE) wall used reinforcement - MSE-T was developed. To build the software, the authors used the database collected at French Research Institute of Motoways and Highways, and National School of Bridges and Roads. The MSE program was developed based on the Visual Studio, using the C # programming language. Calculated result of the software is the corrosion of the reinforcement and service time of the wall. The software was applied to design the retaining wall of Trinh Tung Bridge belonging to the Noi Bai-Lao Cai Highway; then, these calculation results and simulate the corrosion scenarios of reinforced concrete in the wall by FLAC 2D software to calculate the stress-strain, displacement of the wall at the different time. Key words - Mechanically stabilized earth wall, database, MSE-T software, corrosion scenario, service life, Principal component analysis, Response surface.
