Abstract
Combining with soft foundation treatment project with dynamic drainage consolidation method(DDCM) in Guangzhou International Convention and Exhibition Center, an indoor model test is designed according to in-situ construction process. Pore water pressure in saturated soft clay is measured when inserting plastic drainage boards during dynamic compaction and after compaction. The results show that the pore pressure at each location reaches its peak at different times after inserting plastic drainage boards completely. During impact process, the nearer a point is to the impact point, the faster and the greater the pressure increases; under a certain impact number, pore pressure at shallow location tends to increase very slowly; but pore pressure at deep location continues to increase after impacting completely, pore pressure at every location dissipates basically consistent.
