Abstract
Short fiber-mixed reinforced soil has been developed by mixing short fiber, 20 mm to 100 mm in length and 2.3 μm to 230 μm in thickness, with soil generated at construction sites and/or processed soil for stabilizing purposes: 1) to enhance strength, toughness and erosion resistance against rain and running water and 2) to promote its effective use as a construction material which is also expected to be conducive to nourishment of vegetation.
This is to report the result of the trial execution in which the short fiber-mixed reinforced soil made of shirasu (white sand) with short fiber and a small amount of cement mixed together in it, was made effective use for strengthening river dike soil on embankment slopes, though shirasu is generally considered prone to erosion and unfit for vegetation, and also to report the result of the follow-up investigation of the status of the short fiber-mixed reinforced soil observed 6 years after its execution.
