| Abstract: | Based on a major construction project in Shanghai,the ground consists of a silt clay layer in surface and underlying a sandy silt layer,the application of vacuum well dewatering technique in dynamic consolidation ground treatment is introduced.The role of vacuum well dewatering in lowering water level,decreasing water content of shallow soil and accelerating the dissipation of excess pore water pressure is emphatically discussed. |

| Keywords: | ground treatment vacuum well dewatering dynamic consolidation excess pore water pressure |
