In this report, further insight was obtained into earth pressure characteristics of the weathered layer behind slope protection work through laboratory tests based on results from investigations into the actual cutting slopes. Experiments were performed using models built on the measured conditions of weathered layers as determined by the above investigations. The outcome showed that it was possible to reproduce the earth pressure of the weathered layer as obtained from the experiments by considering the friction of the back surface of slope protection work. An evaluation method was then developed on the basis of results from the experiments.
