Study on stability of geogrids-reinforced high embankment

摘要

In order to study stability of geogrids-reinforced high embankment, by indoor direct shear test and pull-off test respectively, interface properities between geogrids and stuffing were studied. The study results indicate that: the variation of water content of stuffing have great influence on geogrids-reinforced high embankment, along with increasing of water content of stuffing, the frictional resistance of reinforced soil interface decreases gradually, relative displacement of reinforced soil increases, soil shear strength decreases, thus it makes that the stable safety coefficient of geogrids-reinforced high embankment shows downtrend.
