| Abstract: | For carrying out the ground treatment of a project in Lianyungang by means of vacuum-surcharge preloading technique,the observation methods for ground surface settlement,horizontal displacement,pore water pressure and groundwater are adopted to monitor the deformation regularity,vacuum transfer regularity and consolidation character during the loading of vacuum load.Then combined with the results from the indoor and site tests for the soft soil before and after consolidation,the comprehensive evaluation is made for the consolidation effect of vacuum-surcharge preloading,so as to provide reliable project examples for the theory study on vacuum-surcharge preloading. |

| Keywords: | soft soil vacuum-surcharge preloading vacuum degree consolidation depth |
