There are two methods of the block retaining wall work, one is the dry masonry block wall structure, and the other is the wet one. The dry masonry block wall structure has the goodness of speed of work and the economically comparison of the wet one. However, dry masonry method has little resistance force against the retaining wall's sliding. We proposed the new method of the dry masonry block retaining wall structure with a resistance plate. This plate makes a passive pressure in the dry masonry block. We investigated seismic characteristics of the dry masonry block retaining wall structure with a resistance plate using the small size model test apparatus. The apparatus is the one dimensional seismic machine. We discussed the influence of the residual displacement of the dry masonry box on materials, position of the box and frequency. We use 1/10 scale model comparison of the in-situ work. We clarified that the influence of the resistance plate makes the residual displacement reduce.
