| Abstract: | Geo cell is a kind of new construction material, which is widely used in the treatment of soft subgrades. On basis of the application of "pre stressed concrete pipe pile + geo cell" in the consolidation of the soft subgrades of passenger dedicated railways, the paper makes a detailed presentation of the features, working mechanisms, calculation methods and construction methods of "pre stressed concrete pipe pile + geo cell". The presented consolidation method has achieved good effects in improving the subgrade's load bearing capacity, minimizing the subgrade's lateral deformation and controlling the soft subgrade's differential settlement. The paper provides a new concept for the treatment of soft subgrades. |
