LATERAL PRESSURES ON RETAINING WALLS DUE TO LOADS ON SURFACE OF GRANULAR BACKFILL

The lateral pressure transmitted through different types of backfill material, characterized through a material parameter e/g and subjected to different types of contact pressure on its surface, is evaluated. The backfill material extending to infinite depth as well as limited by the presence of rigid boundaries having different frictional characteristics is considered. The physical and mechanical characteristics of the granular materials affecting the development of lateral pressures on retaining wall are investigated. The model used in the analysis is found to be applicable to a wide range of materials ranging from solids to liquids. Qualitative numerical results over a wide range of the values of the material parameter (e/g) have been presented in a non-dimensional form to elucidate its influence on this problem. The results are also compared with that of Boussinesq's approach. It is observed that the the softer/looser the backfill, the poorer is pressure transmission in horizontal direction resulting in an overall decrease of the lateral pressure on the retaining structure. The proposed model gives a partial explanation of the divergences between the results of the existing theories and reality. (TRRL)
