NUMERICAL MODELING OF THE LOAD-DISPLACEMENT BEHAVIOR OF ANCHOR WALLS

Finite element analyses of anchor wall behaviour in loose and dense sa nd were carried out using the variable elastic soil model and Lade's e lasto-plastic soil model. The results were compared with data from cen trifugal tests on models of Im high anchor walls. The variable elastic model, incorporating parameters derived from triaxial compression tes ts, yielded results which most closely matched observation. In general , the soil models considered overpredicted observed strength and stiff ness, particularly for walls in dense sand. (C) 1997 Civil-Comp Ltd an d Elsevier Science Ltd.
