The Application of the Capped PTC Pile in Expressway Widening on Soft Foundation
Prestressed Tubular Concrete pile (PTC pile) with individual cap is applied in soft ground treatment in the widening project of Jin-bin expressway. The observed data on embankment settlement, soil pressure, pore water pressure and lateral deformation, investigate the effect of the application of PTC pile in soft ground improvement for extension project of Jin-bin expressway in Tianjin soft area.
