In order to investigate the mechanical response characteristics and reinforcement effect of BFRP(basalt fiber reinforced plastics)anchors under rainfall conditions,a loess-mudstone structure slope was took as a case for indoor physical model tests,and the multi-attribute response data such as slope displacement,BFRP anchor strain and axial force was obtained.It was found that the catastrophic evolution processes of loess-mudstone slope under rainfall conditions are:slope top tensioning →local collapse of slope surface →gully development.The deformation displacement of slope on the side of BFRP anchor reinforcement is smaller than that on the side of steel anchor reinforcement.The bearing capacity of BFRP anchors is successively exerted in time,and the axial force value has the characteristics of scale amplification effect in the model space.The research results can provide a theoretical basis for the reliability optimization design of BFRP anchor.
