Glass Fiber Effect on the Undrained Static Response of Chlef Sand (Northern Algeria)

Abstract

In this article, a laboratory study using a series of 24 consolidated undrained triaxial tests was carried out on samples consisting of two relative densities, reinforced and unreinforced by glass fibers of varying content and subjected to three confining pressures. The results showed that the presence of fibers contributed towards achieving a clear improvement on the undrained shear resistance of the tested sand. It was also noticed that the presence of randomly distributed fibers in the soil mass, provoked a considerable diminution in interstitial pressure, while contributing to the resistance improvement against liquefaction and the optimum of the resistance of fiber is 0.4% for all the performed tests.
