“The mazume-ishi method” is a kind of repair method for castle masonry walls, which is the method to replacing stone that fell from masonry walls. The case of engineering examination for evaluating the stable improvement effect of the masonry walls by this method is not found. In this study, the analysis by the distinct element method (DEM) was carried out on an actual castle stone masonry wall which was repaired by this method. The analytical model was made accurately based on the information of the back side of the stone masonry wall employing the radar exploration. As the result, it was confirmed that this method improves the stability of the masonry walls under static conditions or in an earthquake.
