DEVELOPMENT OF A NEW TYPE REINFORCED EARTH WALL USING IMPROVED SOILS COMBINED WITH GEOGRID

Abstract

A new type of reinforced earth wall was developed, using improved soils combined with geogrid. It had been carried out pull-out tests of the geogrid in improved soils, loading tests on the model and the trial construction of a new type of reinforced earth wall. In this papers, we report the distribution of earth pressures, subugrade reactions and the strain of geogrid of its wall.
As a result, it was confirmed that the earth pressures acting on the concrete panel are negligible due to the effect of the improved soils. In addition, geogrid was found to be subjected to tensile strains, indicating that it is effective in contributing the stability of its wall of this kinds.
