Application Of Combined Anti-slide Structure In Large High Fill Slope Treatment Project

In this paper,the deformation of large-scale slopes with different combinations of anti-skid structures in different combinations is simulated with the background of comprehensive control of high-fill slope in a southwest airport.The effects of the interaction of reinforced soil,anti-slide pile and anchor cable on the deformation of reinforced soil slope are mainly discussed.The following conclusions are drawn:(1)Reinforced soil tendon spacing.In this paper,the effect of the spacing of reinforced soils on the deformation of slope is studied by changing the spacing of reinforced soil.The results show that the deformation and settlement of the slope will gradually decrease with the decrease of the spacing of the reinforced soil,and the deformation of the outermost anti-slide pile will gradually increase.(2)prestressed cable.By changing the anchor stress of the inner row anti-slide pile,the anti-slide pile and the frame structure,it is concluded that the stress of the frame anchor has the greatest influence on the deformation of the slope.The influence of the stress on the deformation of the slope is the smallest.(3)row of double-row anti-slide pile spacing.The relationship between slope deformation and anti-slide pile spacing is obtained by changing the rows of anti-slide piles.In order to find the reasonable row spacing of the embedded double-row anti-slide pile in the slope control,it will provide suggestions for the construction.
