Damage Model of Basalt-Fiber-Reinforced Cemented Soil Based on the Weibull Distribution

This study investigates the mechanical performance and a constitutive model of basalt-fiber-reinforced cemented soil (BFRCS) containing 0%, 0.1%, 0.3%, 0.5%, 0.7% basalt fibers with lengths 3, 6, 12, 20, 35 mm, respectively. Unconfined compressive strength tests were used to examine BFRCS varying fiber contents lengths. The test results demonstrate that content optimal quality is distribution uniformity density have significant impact on BFRCS. Based Weibull for degree damage, damage BFRCS, accounting length content, proposed here. Moreover, in this we explored relationship between scale parameter as well shape length. Furthermore, evaluation methods properties according parameters are discussed. suggest captures stress–strain BFRCS; theoretical strong agreement data obtained.
