In order to study the characteristics of different length and diameter of cement mixing pile on the settlement law of treating soft soil foundation and the influence on ride comfort.Combined with the ac-tual project,different pile lengths and diameters of cement mixing piles are taken as reference factors to conduct finite element numerical simulation analysis.Through the numerical simulation analysis of different pile lengths and diameters of cement mixing piles under unified working conditions,it is concluded that the pile lengths of cement mixing piles have a great influence on the settlement of soft soil foundation,and the length of cement mixing piles increases by 2m.The settlement amplitude of soft soil foundation is reduced by 13%,and the settlement amplitude of subgrade top is reduced by 11%.However,the settlement of soft foundation is less affected by pile diameter.
