| Abstract: | A sampling technology by boreholing in the process of consolidation by vacuum preloading was presented on the basis of field tests. The technology can guarantee the stability of the vacuity, so it can provide a new experimental means for further research about the vacuum preloading method, especially for the study of the variation of geotechnical parameters and consolidation theory in the process of soil consolidation by vacuum preloading. |

| Keywords: | sampling by boreholing process of consolidation vacuum preloading vacuity |
