Report Title : Horizontal Subgrade Reaction for Cantilevered Retaining Wall Analysis (1993), 41 p. (Reprinted, 1995)

Author : W.K. Pun & P.L.R. Pang


This report presents a review of the subject of horizontal subgrade reaction as part of the R & D works to revise Geoguide 1: Guide to Retaining Wall Design. In this report, value of soil deformation parameters relevant to wall analysis are derived using two different approaches, viz. the elastic solution approach and back-analysis of published results of passive earth pressure measurements. The results of the comparison exercises carried out to check the derived deformation parameters values are also presented.
