Abstract
For geotextile-reinforced soil wall, a prediction of deformation characteristic is important for a purpose of serviceability. Usually, this prediction is carried out by FEM. analyses. On the other hand, the purposes of this report are to predict deformation characteristics of geotextile-reinforced soil wall, to estimate tension distribution of geotextiles and to estimate earth pressure against wall, based on limit equilibrium method.For convenience of analyses, the facing of the reinforced soil wall was adopted as discrete type concrete panels. It assumed the condition that the concrete panels were supported from the front side and removed the supports after filling was completed. A trial wedge method by linear sliding (method of Coulomb's earth pressure) was applied to simplify the analysis, based on an equilibrium condition for series of potential sliding surface that originated from connecting part of each panel. Internal stress and deformation behavior of reinforced soil wall were calculated.
