Analysis of the causes of quality accidents in deep filling soil and dynamic compaction foundation in a mountainous area
In recent years,due to the requirements of comprehensive utilization of land and environmental protection,some factories and mining enterprises mostly select the mountainous areas as the construction land,and the original terrain of the proposed area will be transform into a deep land filling base by flat treatment.Dynamic compaction foundation has the advantages of short construction period and less investment,so it has been widely used.Due to the complexity of properties of the foundation with deep filling soil in mountainous areas,some construction quality problems often occur,which makes the building appear uneven settlement deformation,building wall cracking,and the subsidence of the site ground,etc.,serious cases will affect the normal use and safety of the building,the reasons for this are manifold.This paper takes a project as an example to analyze the causes of quality accident of dynamic compaction foundation treatment in mountainous areas,so as to provide reference for later similar projects in the future.
