Abstract：A field test was conducted on a geogrid-reinforced soil wall(RSW) with wrapped face on soft ground. Such items as settlement at the original ground surface，lateral and vertical displacement at the RSW toe，lateral displacement at the RSW face，vertical earth pressure in the RSW and lateral earth pressure along the back of the RSW face and reinforcement strain were analyzed. The working behaviour and the stability of the RSW were discussed. The test results show that the failure of the RSW on soft clay exhibits external instability；the wall surface shows bulging and the maximum lateral displacement occurred at the middle of the full height of the wall；the maximum strain occurred at 0.8 H(H is wall height) distance from the wall surface and ‘0.3H’ method used to predict the location of slip surface and maximum strain is not applicable to the RSW on deep soft clay. The results can be referred for the research，design and construction of the similar projects in the future.
