The nanoscale size of nanomaterial particles increases the specific surface area of the contact material of the material particles,which can develop more usage characteristics.The use of nanomaterials to improve the mechanical properties of soil has been an emerging research topic in recent years.It is still in its early stages and requires extensive research to translate it into practical on-site applications.Based on the current research status of the application of nanomaterials in soil improvement both domestically and internationally,this study analyzes the roles and impacts of different nanomaterials in soil improvement.
