Abstract
Goesynthetic short fiber-mixed reinforced soil construction method is capable of improving and controlling the mechanical characteristics, e. g. apparent cohesion, toughness, and ultimate and residual shear strength, resistance of erosion caused by rainfall and weathering, and such other properties as green vegetation concerning environmental conservation. Moreover the method is applicable to weak strength soil as an effective reuse of surplus material in a construction site, and consequently the technique may fulfill multi-functional performance. However comprehensive understanding and sufficient data are not available yet regarding the internal reinforcing phenomena and mechanism of the fiber-soil particles mixture in which short-length fibers are distributed homogeneously.
In this study a new type of reinforced soil blended with a short-length geofiber with limbs in its normal direction is developed with the intention of increasing its reinforcing effect furthermore and being possible for the natural soil or the fibers to be reused in case of any modification of the geostructure some day. This paper describes the results of effects of limb length of fiber using both a large-scale box shear test and an unconfined compression test.
