Experimental Study on Dynamic Compaction-Plastics Drain Board Method in Backfill Subgrade Reinforcement
Plastics drain board method is one of the most effective ways of reducing excess pore water pressure during the process of dynamic compaction in soft soil subgrade reinforcement. Based on field test in neritic backfilled area of Jinzhou Port 207B berth, the pore water pressure, groundwater level, subgrade bearing capacity and time effect of deformation have been measured and analyzed. The application of dynamic compaction-PDB method makes a mighty advance of the dynamic compaction method, which provides a new way for soft soil treatment in coastal areas.
