Study on the Mixing Properties of Bamboo Fiber and Loose Soil

Abstract

Slope stability is crucial for geotechnical safety. This study evaluates bamboo fiber (BF) as a sustainable reinforcement for loose soils, analyzing the effects of BF content and clay proportion on shear strength. Direct shear tests showed that BF enhances cohesion (2.2-fold increase to 6.37 kPa) and the internal friction angle (48% improvement to 37.7°), with an optimal clay content of 16%. Synergistic interactions between BF and micro-clay particles were quantified via SEM, supporting a proposed micromechanical model for shear failure. These findings demonstrate BF's efficacy in slope stabilization, offering eco-friendly solutions for embankments and tailings dams.
