Research on the"Three Backs"Backfilling Construction Technology for Loess Roadbed
A certain expressway is located in a loess area.In order to ensure the quality of its"three backs"backfilling construction,a series of studies have been carried out based on this project.Through ex-periments,basic indicators such as density and moisture content of undisturbed soil were obtained,and data such as cohesion and internal friction angle were obtained under different moisture content conditions,provid-ing theoretical support for the"three backs"backfilling in loess areas.
