The shallow rapid reinforcement technology based on the vacuum preloading principle is a new technology of rapid reinforcement technique for the new reclamation silt.Relying on Huizhou Quanwan port soft foundation treatment engineering,we study the influence of different drainage plate spacings on the shallow rapid reinforcement effect by the field test.We also study the rules of the process of strengthening about the vacuity under the membrane and the surface settlement and pore water pressure,and analyze the soil physical and mechanical properties,strength and bearing capacity of foundation before and after the reinforcement.
