Study on Seismic Behaviour of Gravity Retaining wall

In this paper discuss the calculating factor of safety. The strategy of gravity retaining walls in an earthquake-prone environment is generally constructed upon still analysis using an equal seismic coefficient. This can be a suitable approach, provided that the seismic coefficient is strong-minded from a rational analysis of real dynamic behavior. The report discusses the seismic strategy of gravity walls retaining rough backfill with no hole water. The general features of behavior are exemplified by field skills, outcomes from workroom model tests and from theoretical analyses. Both the conventional technique of design and the Richards-Elms (1969) method, based upon a similarity to a sliding block, are reread. An inadequacy of the sliding block similarity is discoursed, and corrections obtained using a two-block model are presented. Numerous birthplaces of uncertainty are examined in feature. The random nature of ground motions, uncertainty in resistance factors, and prototypical mistakes, including the important effect of deformability in the backfill. All of these results are then joint to improvement a probabilistic course of action for estimate seismically induced displacements of ramparts and an improved version of the Richards-Elms procedure of design. The risk that walls planned by the conventional method might experience unnecessary displacements is analyzed.
