ABSTRACT

This paper presents the results of a parametric study, carried out to investigate the response of a simple embedded retaining wall analysis to changes in pile coupling spring properties. The study was carried out using a grid with a single soil type and a simple excavation and propping sequence. Two walls were analysed, one representing a flexible sheet pile wall and the other representing a stiff concrete wall. For each wall type, six series of runs were carried out, with only one coupling spring parameter being varied in each series of runs. The results of the analyses are summarised, and the influence of each coupling spring property upon wall and soil behaviour is discussed, in terms of the specific analysis carried out and in general terms. Typical values of coupling spring properties for retaining wall problems are also discussed briefly.
