Abstract
Pullout resistance of reinforcement was very important factor to design the reinforced earth wall structure. Reinforced earth walls with discrete-layout reinforcements were constructed by considering the dilatancy effect. A series of small model test was performed to compare deformation behaviors. Difference in deformation behaviors of reinforced earth walls between normal-layout and discrete-layout reinforcements was discussed. The width of model reinforcement was changed among three types of the width such as full width, 10%, and 20% narrowing. In conclusion, horizontal displacement of front panel in 10% narrowing was smaller than that full width. The discretelayout has an advantage to reduce the horizontal displacement by selecting the reasonable width of reinforcement.
