Field performance of a geotextile reinforced soil wall with concrete facing blocks

To investigate the wall-facing effects on geotextile reinforced soil wall, on-site performance tests were conducted using 8-meter high vertical reinforced soil wall with a large concrete block facing. From the test results the maximum reinforcement strain was approximately 1% and the facing’s horizontal displacement 6.5 cm, both measured at the time of completion of construction. These results are acceptable for the stability of the reinforced soil wall. Both settlement and displacement measured at the time of approximately 160 days after the completion of construction suggest that the wall is in a stable state. In general the reinforced zone behaves as a rigid body, however that hypothesis is not justified for this performance test.
