Dynamic analysis on the stability of high reinforced soil slope under seismic effects

At present, there is a lack of reasonable design and calculation method for the high slope of reinforced soil. Based on the strict mechanic theories, the paper adopts FEM strength reduction to carry out static analysis and dynamic analysis under seismic effects on the high reinforced soil slope in Hechi Airport, Guangxi Province. The calculation results indicate that both the dynamic and static safety factors and the length of reinforced belt can satisfy the design requirement. The monitored data in the field are in coincidence with the result of numerical calculation, and the engineering project is stable and reliable after the completion of construction.
