We were able to place the static load (60ton steel plate) and Dynamic load (Dump truck weight about 20ton) on the Fabric reinforced wall which had been completed in Feb. 1986 in order to evacuate the critical condition of the wall's behavior. We measured their displacement in horizontally and vertically their settlement by the buried instrument (horizontal inclinometer, pressure gauge and horizontal displacement gauge, etc.). Through these experiment, we learn that the effect by Dynamic loads was smaller and the face of wall moves forward by bigstatic loads near the top of wall. We recognized that nowadays Reinforced Fabric wall designmethod is safer than anticipated condition and Safety Factor about their pullout resistance and Rupture resistance Safety Factor 1.5 is reasonable. The displacement and vertical pressure occured during their construction was larger than those measurement this time so we convinced that the constructability and survivability is more important.
