The invention provides method of preventing changes in the nature of a ground wherein, with a consolidation yield stress profile lying within a pre-consolidation region on or above a profile line of an effective soil covering stress of a ground with a piling structure laid thereon, said effective soil covering stress of said ground with a piling structure laid thereon being calculated with respect to a foundation ground on which a piling structure is scheduled to be laid, by plotting an effective soil covering stress profile of an original ground and using said profile line as reference, on condition that a load of said piling structure is transmitted as such through said original ground, soil forming a ground to be reconstructed is improved without disturbing said ground to be reconstructed, and said ground to be reconstructed is in situ subjected to a single concurrent operation involving four principles for reconstruction of a soft ground, (1) consolidation and dehydration, (2) drainage, (3) solidification, and (4) replacement (called an instantaneous consolidation method), so that the ground can be improved within 24 hours, thereby preventing subsidence of said ground due to consolidation, and deformation and displacement of surrounding ground layers or structures built up thereon.
