PREDICTION MODEL OF REINFORCEMENT LOADS FOR GEOGRID REINFORCED SOIL WALLS WITH COHESIVE SOIL BACKFILLS

Abstract

Proper estimation of soil reinforcement loads is key to accurate internal stability design of geogrid reinforces soil walls. In this paper the estimation model of soil reinforcement loads, called K-stiffness Method as proposed by Allen et al. (2003) is extended to the case of cohesive soils. Design methodology with the modified method also discussed. Modified K-stiffness Method can result in substantial cost saving.
