Closure to 'Predicted Loads in Steel Reinforced Soil Walls Using the AASHTO Simplified Method' by Richard J. Bathurst,Axel Nernheim, and Tony M. Allen

摘要

1. The writers do not agree with the discussers that the three walls identified as unusual should be omitted from calibration of the simplified method. The criteria for selection of the metallicrnreinforced soil walls in the database were as follows: (1) the structures were well-constructed; (2) they behaved well; (3) they had well documented soil properties, and; (4) they were carefully monitored to deduce reinforcement loads under operational conditions. The three steel strip walls noted by the discussers have two common and consistent quantifiable features: (1) they were constructed with soils having a peak friction angle greater than 45°; and (2) the ratio of measured to predicted reinforcement loads with depth below the crest of the wall was consistent between the three walls.
