EVALUATION OF STEEP CUT SLOPES IN POORLY CONSOLIDATED SEDIMENTS

The performance of newly constructed, steeply cut slopes in poorly consolidated silts, sands, and gravels along a 5 mile length of road was observed and evaluated over a 5 year period. Color aerial photography supplemented by ground level photos facilitated reconnaissance geologic mapping. The study objective was to relate damage incurred by the slopes (slides, slip outs, revelling, etc.) to the local geology, slope ratios, bedding, and precipitation. Costs of maintenance and remedial measures incurred were determined and added to theoretical costs had flatter, more stable slopes been constructed initially. Recommendations are made for cut slope design based on findings of the study. /Author/
