Abstract: The design method of reinforced high earth retaining wall based on limit equilibrium theory is expounded with the high retaining wall (60m) at Shennongjia airport as an illustration. To ensure the safety and rationality of the design, strength reduction and finite element were employed to analyze the stress-strain and stability of the retaining wall. Monitoring points were also arranged in the key sections of the retaining wall. The monitoring data revealed that the deformation of retaining wall was small, the deformation rate showed a tendency of convergence, and the stress and strain were all stable. The rationality of design method was proved by the monitoring results. This research provides reference for similar projects.
