Pseudo-Dynamic Active Earth Pressure on Battered Face Retaining Wall Supporting c-Phi Backfill Considering Curvilinear Rupture Surface

In the present analysis, using the horizontal slice method and D'Alembert's principle, a methodology is suggested to calculate the pseudo-dynamic active earth pressure on battered face retaining wall supporting cohesive-frictional backfill. Results are presented in tabular form. The analysis provides a curvilinear rupture surface depending on the wall-backfill parameters. Effects of a wide range of variation of parameters like wall inclination angle (alpha), wall friction angle (delta), soil friction angle (Phi), shear wave velocity (V-s), primary wave velocity (V-p), horizontal and vertical seismic accelerations (k(h), k(v)) along with horizontal shear and vertical loads and non-linear wedge angle on the seismic active earth pressure coefficient have been studied.
