• Abstract:
  Evaluation of the design methods involved a comparison of results calculated from the popular design methods BS 8006-1, EBGEO, CUR226, and the Federal Highway Administration (FHWA) for three key design parameters (load efficacy, differential settlement and reinforcement strain). The measured data were available in the literature, including 24 full-scale experiments and four model tests. The comparison results revealed variations and inconsistencies of the calculated results among the design methods. Numerical analyses were also performed for two case studies, and their results were compared with the results from the design methods. Methods CUR226 and FHWA comparatively more accurately predicted all three design parameters, while BS 8006-1 overestimated all these parameters.
