摘要

Based on a lot of achievement, the excellent stability of reinforced wall during the earthquake has been suggested. On the other hand, it is important to confirm the performance when a soil structure is designed. Actual size vibration test with large scale shear box was done to research the dynamic behavior of the "Multi-Anchored Reinforced Wall(MARW)". The acceleration of each part, the tension of the reinforcement material, the vertical load of the wall and the amount of deformation were measured at MARW of the height 5m during the vibration. According to the test results, following dynamic behavior of MARW were confirmed. 1)A reinforced field is unified action. 2)Increase in tension of reinforcement(Tie-bar) during the vibration is big in the connection point of the Tie-bar and the wall. 3)Increase in tension of Tie-bar during the vibration is as big as it is deep. 4)Increase in vertical load of reinforced field is big around the toe. 5)Residual stress and deformation after acceleration over 400gal are extremely small.
