Retaining Structures-Rankine and Coulomb Theories
Rankine’s theory calculates lateral earth pressure solely based on friction angle, assuming the wall is smooth. Coulomb’s theory allows rough wall …

Retaining Structures-Lateral Pressure
Due to interparticle friction, soil slides at an angle equivalent to its internal friction angle. Thus, lateral pressure exerted on structure is de…
