Aiming at the stress characteristics of h-type anti-slide piles under the load of the top of the slope,the mechanism of the front pile and the rear pile,the bending moment of the pile shaft and the distribution of the soil pressure in front of the pile are analyzed through scale model test in laboratory.The results show that under the load of the top of the slope,the bending moment of the pile shaft of the rear row pile is increased first and then decreased with the increase of the pile burial depth,and the peak moment appears near the pre-set slip surface.The bending moment of the front pile is increased with the depth of the pile,and the maxi-mum value appears at the joint of the pile top and beam.The distribution of earth pressure in front of the rear pile is increased with the increase of the load at the top of the slope,while the relative change range of the two measuring points in the upper part is small.In the position below the link beam,the trend of earth pressure distribution in front of the front pile is basically the same as that of the rear pile,while the position of the link beam is small.
