%X The stress form, internal force distribution and failure mode of  anti-slide anchor piles of different structures are compared and analyzed by measuring the soil resistance, bending moment of piles body and the strain of anchor in three model tests of reinforcing loess landslide by different pile-anchor structures (common anti-slide pile and anti-slide anchor  pile). Results show that 1) in the prevention and control of loess landslide, the stress of anti-slide anchor  pile displays an "S" shape, and the displacement of pile top is smooth and continuous, and the distributions of soil resistance and bending moment of pile body are more uniform; 2) increasing the number of anchors at the top of pile could increase the anti-slide force; 3) the failure mode of common anti-slide pile is mainly plastic single hinge damage, while that of anti-slide anchor  pile is mainly single hinge (or double hinges) damage; the main failure of anchor is bending-shear slip damage, and that of the soil around pile is mainly plastic failure of soil arch. The research results provide technical support for the design theory of anti-slide anchor  pile in loess landslide prevention and control.
