| Abstract: | The mechanism of the land subsidence in Tianjin Binhai New Area was analysed according to the observation about 15 years.The land subsidence was influenced by the shallow underconsolidated soft soil's drainage solidifying and in-depth soil moisture release compression.The influence of the ground water levels fall to the ground subsidence was calculated and surface subsidence control measures were put according the exploring of on-site hydrogeology information and laboratory experiment. |

| Keywords: | land subsidence additional stress drainage consolidation underground water level |
