Abstract

The purpose of this study was to evaluate the properties of unconfined strength of dry soil which was reinforced with polypropylene fiber. It is found that unconfined compressive strength and strain of dry soil without fiber were decreased as water content was increased. As mixing ration of fiber was increased , unconfined compressive strength and failure strain of dry soil reinforced with polypropylene fiber were increased. When mixing ration was larger than 0.5 % , unconfined compressive strength was gradually increased. The longer fiber was, the largest post peak strength was obtained and the larger strain was reached. Tensile strength of dried fiber reinforced soil was larger than that of dry soil without fiber.
