Rehbann's / Poncelets Theory
Rebhann (1871) gave this graphical procedure for locating the slip plane and determining the total active earth pressure according to Coulomb’s wedge theory. Procedure:- 1) Draw A retaining wall having height H i.e. AB 2) Draw three lines Ground Line ( ß @ with horizontal) Failure Line ∅ Earth pressure line Ψ 3) Through point A Draw a line parallel to Ψ line which cuts BD line at point C. 4) Through C draw perpendicular line CE which cuts an arc at E. 5) Join BE line consider BE as a radius and B as a center draw an arc through E which cuts at point F on BD line. Through F draw a line parallel to Ψ line which ...
