SOIL PRESSURE AND STRESSES ON WOOD FACED RETAINING WALL WITH BAR-MAT ANCHORS

This report presents the results of laboratory testing and short-term field monitoring of an instrumented wood-faced mechanically stabilized embankment constructed with steel bar-mat reinforcement. This retaining wall supported an embankment, allowed traffic through construction, and eliminated a costly detour. Wall construction was rapid, economical and provided good performance. Strain gage measurements on plywood face panels from laboratory vacuum test loadings and under actual overburden conditions provided good correlation for estimating lateral soil pressures. These estimated values were confirmed by strain gage measurements on steel bar-mat reinforcement. Pressure cells were unreliable in measuring lateral soil pressures. The resluts of instrumentation suggest a uniform lateral oil pressure distribution behind the wall face. (Author)
