Document Type and Number:
Japanese Patent JP2010511112
Kind Code:
A
Abstract:
A method for treating soft soil, including dividing a site into a plurality of subsections, investigating profile of the soft soil in each of the plurality of subsections, estimating expected settlement of the soft soil in each of the plurality of subsections, installing a plurality of water-tight systems around the site to block seepage of ambient groundwater from entering the site, installing a plurality of vacuum pipes in the plurality of subsections in a layered matrix form, connecting the plurality of vacuum pipes to a vacuum system via a plurality of ground horizontal pipes, placing a piezometer in each soil stratum, probing ramming energy thereof by conducting dynamic trials, measuring pore water pressure dissipation of each soil stratum to determine the spacing of the plurality of vacuum pipes, and performing a plurality of cycles of vacuum-compactions in each of the plurality of subsections.
