Abstract:As a new subgrade filling material,the foam light soil has the characteristics of light weight,fluidity,adjustable strength and density,convenient construction and environmental protection,and has been gradually popularized and applied in the aspects of soil roadbed treatment,subgrade widening,post treatment of bridge abutment,and off-load backfill of metro engineering now.Relying on Guangming Expressway Luoge Toll Gate Square,the post-construction settlement control and treatment effect of large-volume cast-in-situ foam light soil are studied and evaluated from the aspects of design and construction process control,and settlement monitoring after traffic.
Keywords:foam light soil  large volume  settlement  deformation joint
