Study on observational procedure for soil-reinforcement method with steel bars.

The design for reinforced cut slope with bars is not always reliable due to the many unknown soil properties of natural ground. It is considered that observational procedure is one of the methods to solve this problem.The present paper is concerned with analysis method for observational procedure on reinforced cut slope. The authors try to explain the results of field loading tests on actual-scale specimens and the behaviors of the actual, reinforced cut slope by two analysis; FEM considering slip joints and slope stability analysis method considering extention of bars.As a result, it was proved that both analysis methods are applicable to observational procedure of soil-reinforced earth method.
