Abstract

Geogrids and geotextiles' shear behaviors were evaluated after installation damage testing. Frictional coefficients of resistance to direct sliding ($f_{ds}$) were estimated by theoretical shear analysis. The shear strength of the damaged geogrid decreased under a high normal stress of 150 kPa; that of the geotextile decreased with increasing normal stress. fds values were found to be lowered by installation damage, through comparison of $f_{ds}$ values calculated by direct theoretical shear analysis before and after installation damage.
