STRUCTURE ON SOFT GROUND USING A COMPENSATED FOUNDATION AND IMPROVED SURFACE LAYER AND CONSTRUCTION METHOD FOR THE COMPENSATED FOUNDATION

摘要

The present invention relates to a structure on soft ground using a compensated foundation and an improved surface layer and a construction method for the compensated foundation comprising a step of analyzing the strata of soft ground; a step of excavating soil; a step of compacting soil; a step of filling the excavated area with the excavated soil; a step of calculating an allowable bearing capacity and checking whether the allowable bearing capacity is enough to bear a design load; a step of forming an improved surface layer; a step of increasing the depth of the improved surface layer for areas expected to have abnormal settlement; a step of determining a design load and designing a foundation area; a step of forming a compensated foundation; and a step of forming a foundation and a bottom floor and constructing a building or a structure on the top of them. Therefore, the present invention prevents differential settlement after the construction of the building or the structure by compacting the excavated surface and applying surface improvement materials to the excavated surface.
