| Abstract: | Aiming at the characteristics of soft soil foundation, the cement mixing pile composite foundation is used to treat the road section in order to reduce the post-construction settlement and to improve the bearing capacity of foundation. Relying on the road construction project in front of the railway station in Hanjiang District of Putian City, the influence of factors such as the arrangement spacing of cement mixing piles, pile diameter, pile length and cement soil strength on the characteristic value of bearing capacity of single pile and composite foundation and the subgrade settlement is analyzed to achieve the goal of reasonable optimization of design parameters and cost saving in practical projects. |

| Keywords: | cement mixing pile vertical bearing capacity of single pile bearing capacity of composite foundation post-construction settlement |
