Compute the passive pressure intensity when the backfill has unit weight of 18 KN/m^3 and height of wall is 6 m. The angle of internal friction is 300. The backfill has surcharge of 36 KN/m^2.
(a) 378 KN/m^2
(b) 432 KN/m^2
(c) 875 KN/m^2
(d) 972 KN/m^2
I have been asked this question in exam.
My query is from Earth Pressure Problems topic in portion Failure Envelopes & Earth Pressure of Geotechnical Engineering II
