Research on the Effect of Cement Mixing Pile in Treating Soft Soil Foundation of Roads
In order to explore the treatment of road soft soil foundation,this article adopts cement mixing piles as the main treatment method,and carries out replacement and filling treatment and cement mixing pile reinforcement on the foundation.And analyze the trend of the change in filling height with the cumulative number of days.The research results indicate that in the initial stage of filling,the bearing capacity of the foundation gradually adapts to the increase of filling soil,and the settlement rate remains at a relatively low level.However,as the filling work continues to advance,the settlement rate significantly increases.Within 90 days of completion of filling,the settlement trend has gradually slowed down and the bearing capacity of the foundation has stabilized.In addition,within a 5m range of the pile top area,the settlement is most significant,with the maximum settlement occurring at the pile top position.This is mainly because the soil in the pile top area is suppor-ted by the pile body and also bears pressure from the upper filling soil.
