<P>PROBLEM TO BE SOLVED: To provide a shallow ground improving method for alleviating sinkage of an upper building and input vibrations to the upper building, reducing the construction cost compared with a conventional art, and improving an effect of preventing deformation of an improved layer. <P>SOLUTION: In the shallow ground improving method, an integrated improved ground is formed by laying a sheet of geotextile on a leveled ground surface, placing dry mixed mortar, and bonding foamed resin plates to each other. When the ground is particularly soft, more stable improved ground is formed by injecting a chemical liquid or laying a plurality of geotextile sheets. Further, when improvement in vibration control performance is required, a vibration control material is arranged between the foamed resin plates. <P>COPYRIGHT: (C)2010,JPO&INPIT |
