This paper shows an effect of steel chain on reinforcement of fill based on pull out test results of large scale. The pull out resistance of steel chain is taken account apparently by dividing into the two components, role of inner frictional angle and dilatancy effect. Tests were conducted by combining different kinds of chain shapes and fill soils, and comparing with pull out resistance of different reinforcement materials in the markets. A basic concept in this study is a frictional correction factor modified by the reference pressure of 100kN/m<SUP>2</SUP>. This factor is clearly described to have the dilatancy effect similar with the behavior of compacted soils. And the governing equations are proposed individually for the each role of inner frictional angle and dilatancy after the phenomena in the test results is reviewed.
