Interface shear strength between slender bamboo rod and ruin soils with high plasticity

摘要

For underground earthen sites in humid environment, its preservation is more difficult than the ones in northwest arid region. One reason is that the changing of existing environment, especially the changing of the groundwater resulting in the local cracks and creep-sliding disease of the underground earthen sites. In the study, according to the basic principles of protection and reinforcement of earthen site, the flexible bamboo rod was employed to intend to treat the creep-sliding disease of the underground earthen sites after excavation. The interfaces shear strength between slender bamboo rod and ruin soils were investigated by laboratory pullout tests and direct shear tests. The results will benefit for further study on the application of the slender bamboo rod for reinforcing the earthen sites in humid circumstances.
