Abstract
Full-scale loading tests on sand embankments which were reinforced with geotextiles were carried out in order to investigate the reinforcing effect of geotextiles.
Test conditions were as follows. (1) Geotextiles (Hard type, Soft type). (2) Inclination of slope (1:1.5, 1:1). (3) Loading position (top of slope, 1m from the top) (3) During the loading tests, the surface deformation of the slope, the stress of the geotextiles and the vertical loading pressure were measured.
The test results showed that the condition of the loading position was most significant.
In the case of loading on the top of the slope, the effect of geotextile reinforcement was noticeable. On the other hand, backside loading test results didn't show a clear difference in the load-settlement curves between reinforced embankment and un-reinforced one.
