| Abstract: | The article sets forth the technical difficulties of the vacuum and heaping combined reinforcing soft subgrade technique in the soft subgrade treatment of the expressway in the connecting line test section at the south bank of Hangzhou Bay Crossing-sea Bridge, that is, the sealing and vacuum level of the reinforced area is effectively transmitted into the deep part of the soil through the drainage plate. At the same time, based on the former practical experience, the problems paid attention to every construction links are summed up and the relative measures are taken so as to aid the application of this method. |
