EARTH PRESSURE ON RETAINING WALL NEAR ROCK FACE

by ZHUANG, JUN

Abstract (Summary)
There are always cases in which retaining structures have to be constructed close to a stable rock face. In such cases, the fill between the retaining structure and the rock face is partly supported by friction on the wall and the rock face; subsequently, the theoretically assumed wedge of sliding soil cannot develop, and the vertical stress in the fill and the horizontal stress on the structure are reduced. Finite element analyses (FEA) were performed for this thesis to evaluate the effect of the interface friction on the magnitude and the distribution of the lateral earth pressure acting on the retaining structure. The analyses show that Coulomb's theory is very conservative and that modified silo theory can be used to evaluate the lateral earth pressure when the fill width is small. Finite element analyses also show that different base material and the friction angle between the fill-base interface may influence the magnitude and the distribution of the lateral earth pressure to a great degree.
