Research of Geo-Grid′s Application in Biotechnical Slope Protection

Based on the study of the mechanism of biotechnical slope protection,mechanical model were developed in the condition of surface soil reinforced with herb-root in geo-grid.A new slope protection technology—geo-grid flexible retaining wall was brought forward.The design and compute methods of geo-grid flexible retaining wall were given and the effect of its application in Jilai freeway is good.
