Taking the typical saturated moisture content clay slope of Shangrao,Jiangxi Province as the research object,a set of finite element model of anti-slide piles was established,and the influence of pile lengths,diametures and positions on the stability of anti-slide piles was analyzed.The research results show that the reinforcement of anti-slide piles can ef-fectively reduce the plastic deformation of this kind of clay slopes,reduce the total slip amount of slopes,and improve the stability of slopes.Within the range of 10-18m pile length,the slope safety factor is positively correlated with the pile length,but when the pile length exceeds 18 m,the factor of slope safety increases slowly,and the reinforcement effect of anti-slide pile does not change significantly.When the pile diameter increases between 0 and 2 m,the total slip displace-ment of the slope decreases.However,when the pile diameter exceeds 2 m,the total slip of the slope is not obvious,indi-cating that the anti-slip effect of the slope is not significantly increased with the increase of the pile diameter at this time.As the distance between the pile position and the foot of the slope gradually decreases,the total slip of the slope is also decreasing.It is suggested to coordinate the length,diameter and pile position in the design of anti-slide piles,so as to meet the reinforcement needs of cut slope while achieving economic effect,reducing the waste of materials and the diffi-culty of engineering works.
