摘要

Apus bamboo (Gigantochloa Apus) is one of predominant vegetation in Indonesia. Direct shear test with large box sample was utilized to investigate shear strength behavior of Apus bamboo reinforced soil. Soil-root volume ratio is proposed to quantify root density at soil mass. The results show that peak shear strength of bamboo root reinforced soil increase with increasing soil-root volume ratio. Their relationships could be approached linearly. Though soil-root volume ratio investigated was only up to 5%, it generated up to 55%additional peak shear strength.
