Reinforced Soil wall are designed with various facing options such as Segmental panel, full height panel, Gabion, welded wire mesh and block. Facings are selected with the consideration of connec-tion, compatible with and vice versa. There are majorly two type of connections are considered, for Rein-forced soil walls, i.e. frictional and positive connection. For positive connection reinforcement are con-nected with the connection such as bodkin, tie and hooks, nut and bolt etc. Frictional connections are connection which are purely designed considering long term connection strength with the interface be-tween geogrid and facing. Here the aim of study is to check the designs for Reinforced soil wall with block facing, with consideration of secondary geogrid for connection and compared with the design of re-inforced soil wall without consideration of secondary geogrid, for connection. For comparison, seismic zone III (as per IS 1893, Indian standard) will consider for various design heights and compare the re-quirement of reinforcement and tensile strengths, in all cases. Merits and demerits are discussed in detail for the use of frictional connection, for higher seismic zones with the use of rod / pins etc., for additional resistance.
