The present study perta.ns to the trila.er gra.hene in the presence of spin orbit coupling to probe the qua.tum spin/va.ley Ha.l effect. The spin Chern-number Cs for energy-ba.ds of trila.er gra.hene ha.ing the essence of intrinsic spin-orbit coupling is a.a.ytica.ly ca.cula.ed. We find tha. for ea.h va.ley a.d spin, Cs is three times la.ger in trila.er gra.hene a. compa.ed to single la.er gra.hene. Since the spin Chern-number corresponds to the number of edge sta.es, consequently the trila.er gra.hene ha. edge sta.es, three times more in compa.ison to single la.er gra.hene. We a.so study the trila.er gra.hene in the presence of both electric-field a.d intrinsic spin-orbit coupling a.d investiga.e tha. the trila.er gra.hene goes through a.pha.e tra.sition from a.qua.tum spin Ha.l sta.e to a.qua.tum va.ley Ha.l sta.e when the strength of the electric field exceeds the intrinsic spin coupling strength. The robustness of the a.socia.ed topologica. bulk-sta.e of the trila.er gra.hene is eva.ua.ed by a.ding va.ious perturba.ions such a. Ra.hba.spin-orbit （RSO） intera.tion αR, a.d excha.ge-ma.netiza.ion M. In a.dition, we consider a.theoretica. model, where only one of the outer la.ers in trila.er gra.hene ha. the essence of intrinsic spin-orbit coupling, while the other two la.ers ha.e zero intrinsic spin-orbit coupling. a.though the first Chern number is non-zero for individua. va.leys of trila.er gra.hene in this model, however, we find tha. the system ca.not be rega.ded a. a.topologica. insula.or beca.se the system a. a.whole is not ga.ed.
