ANALYSIS AND DESIGN OF HIGHWAY CUTS IN ROCK

Following the recommendations of the study reported by Hamel and Flint 1969, PDH Research Project No. 41472, evaluation of potential sliding areas on LR 1021 was made. The purpose of this study was to develop design criteria for cut slopes in rock based on data obtained from instrumented slopes, supplemented by laboratory testing of representative samples. However, due to construction delays a decision was made to terminate the subject project until 1976. For this reason, only the preliminary study of the slump bench near station 342 was made and reported.
