In order to study the influence of compaction pile parameters on the reinforcement effect of loess foundation,this paper takes the construction project of modern agricultural innovation and entrepreneurship base in Lanzhou New Area as the research background.Based on the finite element software,the numerical model of compaction pile composite foundation is established to study the influence of compaction pile length,pile diameter and pile spacing on foundation settlement.Finally,the relationship between three parameters and the final settlement is analyzed.The results show that:The settlement of foundation is negatively correlated with the length of the compaction pile,negatively linear with the diameter of the compaction pile,and positively linear with the spacing of the compaction pile;The compaction pile length of 6 m is the mutation point of foundation settlement,which may be related to higher bearing capacity of the lower soil layer than that of the upper soil layer.
