Ba.k-to-ba.k mecha.ica.ly sta.ilized ea.th wa.ls （BBMSEWs） a.e encountered in bridge a.proa.hes, ra.p wa.s, rockfa.l protection systems, ea.th da.s, levees a.d noise ba.riers. However, a.a.la.le design guidelines for BBMSEWs a.e limited a.d not a.plica.le to numerica. modeling when ba.k-to-ba.k wa.ls intera.t with ea.h other. The objective of this pa.er is to investiga.e, using PLa.IS code, the effects of the reduction in the dista.ce between BBMSEW, the reinforcement length, the qua.ity of ba.kfill ma.eria. a.d the connection of reinforcements in the middle, when the ba.k-to-ba.k wa.ls a.e close. The results indica.e tha. ea.h of the BBMSEWs beha.es independently if the width of the emba.kment between mecha.ica.ly sta.ilized ea.th wa.ls is grea.er tha. tha. of the a.tive zone. This is in good a.reement with the result of FHWa.design guideline. However, the results show tha. the FHWa.design guideline underestima.es the la.era. ea.th pressure when ba.k-to-ba.k wa.ls intera.t with ea.h other. Moreover, for closer BBMSEWs, FHWa.design guideline strongly overestima.es the ma.imum tensile force in the reinforcement. The investiga.ion of the qua.ity of ba.kfill ma.eria. shows tha. the minor increa.e in emba.kment cohesion ca. lea. to significa.t reductions in both the la.era. ea.th pressure a.d the ma.imum tensile force in geosynthetic. When the dista.ce between the two ea.th wa.ls is close to zero, the connection of reinforcement between ba.k-to-ba.k wa.ls significa.tly improves the fa.tor of sa.ety.
