Abstract
In order to predict distribution of vertical stress increment due to pulling-out of reinforcement, the cavity expansion theory was applied to the pull-out test results. First, the approach for applying the elastic solution of the cavity expansion theory which can evaluate stress state when the internal stress of a thick-walled cylinder increases was shown. And the result of the pull-out test was extended and distribution of vertical stress in a reinforced soil wall structure was predicted. As a result, at the place away from the reinforcement about 70cm or more, it was shown that vertical stress increment becomes quite small.
