Research on Construction Technology of Soft Soil Foundation Pit Changing-Filling Method and Support

In combination with the geological exploration report,this paper analyzes the geological situation of a certain project so as to be aware of the characteristics and difficulties of the project.Through comparing a variety of pit supporting schemes,it chooses a reasonable construction scheme that deals with the pit slope by filling weathered sand and ballast to the soft soil slope and combining anchor bars and soil nailing support system,and discusses the construction technology of the soft soil foundation pit changing-filling method and support.Monitoring the completion of the project proves that the construction technology is effective for the treatment of soft soil foundation pit slopes.
