Against loess landslide control, two physical model tests of loess landslide have been completed. Test I is model test of loess landslide with preset slide surface, loading on the top of the slope; test II is based on test I, adding the cantilevered anti-slide pile before the slope. The preset slide surfaces are composed of double-layer plastic films. Two testing processes and piling-up weights methods are the same; the only difference is adding cantilevered anti-slide pile and pressure cells placed around the piles. Through analyzing the results of the test I, similarity shear strength parameters of the preset slide surface are determined. In the test II, through analyzing soil displacement before the pile, limit state of loess landslide with the cantilevered anti-sliding model pile is established and load value is obtained, which provides references and bases for subsequent experimental study.
