Interaction between earth pressures against a reinforced retaining wall and tensile forces of reinforcements

摘要

In order to evalaute stability of a reinforced retaining wall, it is required to know the relations between displacements of a wall, tensile forces of reinforcements, earth pressures against the wall, fricitional forceson reinforcements and so on. In this study these relations were observed i nthe series of centrifuge model tests taking into account strain levels of the backfill soils. And then the centrifuge model tests were simulated by two-dimensional FEM analysis considering the discontinuity between reinforcement/soil and facing/soil. As a result, the earth pressures against the wal and the tensile stresses of the reinforcements were evalauted as the functions of the wall displacements.
