  • Investigation Of Foundation Soil And Reinforcement Of Foundation Soil By Compacting Or Drainage (AREA)

Abstract

PURPOSE: To raise the shear and conpressive strength of a soil by mixing a short fiber material composed of a synthetic fiber, a synthetic resin, or a metal fiber with the soil and sand in such a way that the short fiber material is irregularly dispersed and orientated in the soil and sand, and also supply the reinforced soil simply and at low cost.
CONSTITUTION: A reinforced soil 2 is placed on the back side of a retaining wall 1. The reinforced soil 2 contains 5wt% short fiber material composed of a synthetic resin fibers 0.05mm in thick, 1.0mm in width, and 50mm in length, with an oblong cross section, dispersed and orientated irregularly in soil. When a condition that the soil and sand are stabilized and loads are equally applied on the soil and sand is reached, a frictional action is acted between the soil and the short fiber material and the short fiber material is linearly dispersed and orientated by the tensile force of soil and sand during the moving and stabilizing processes. Thus, during the moving process of soil and sand, a high tensile strength is exhibited and highly uniform shear and compressive strengths are produced.
