Abstract
A two dimensional plane-stress finite-element type of analysis is pre-sented to predict the behaviour of geogrids embedded in sand under pullout loadingconditions. In the analysis the interactions between soil and geogrid are simulatedby non-linear springs. The stiffnesses of the springs can be determined from simpletests in a specially designed pullout box. The proposed finite element (FE) analysis isapplied to interpret test results from a large scale pullout test rig. The predicted be-haviour of the geogrid under pullout load agrees well with the observed data includingthe load-displacement properties, the displacement distribution a/ong the longitudinaldirection and the mobilisation of the frictional and bearing resistance.
