Based on a municipal engineering project in the east new district of Chengdu City,this paper proposed a treatment technology that combines shallow replacement with riprap compaction.Through the settlement prediction and stability analysis of the treated subgrade,it can be seen that the settlement in the filling period and the sliding safety factor of the subgrade were mainly affected by the subgrade filling height,and the post-construction settlement of the subgrade was affected by the soft foundation depth.By monitoring the settlement and displacement during the construction period,the settlement occurred during the subgrade filling period,and the interval length of the filling period was an important factor affecting the settlement rate.This paper can provide a reference for similar projects.
