Prevention of the shape change of the clay soil caused by the rebound of roads, banks, and landfills, and disaster prevention methods for earthquake disasters

摘要

1. Technical field to which the invention described in the claims belongs;TECHNICAL FIELD [0001] The present invention relates to a method for preventing a shape change of a clay soil generated on a road, a bank, a composition ground, and an earthquake disaster prevention method.;2. Technical Problems to be Solved by the Invention;The present invention relates to the problems of the respective problems of the compaction time, the construction environment, the design supervision and construction management, the dislocated ground caused by the slip failure of the ground, the restoration or reinforcement of the ground or structure suffered by the earthquake,;3. The point of the solution of the invention;According to the present invention, the distribution of the effective soil stress of the original soil is floated, and the effective soil stress of the covered soil is obtained by letting the load of the covered soil be directly transmitted to the ground surface based on the distribution line, Distribution of stress The distribution of the compaction yield stress in the compaction area in the range of the line or over the effective soil stress of the embankment soils The improvement of the soil itself without disturbing the ground of the target and the improvement of the soft ground The compaction dehydration, The basic principles of solidification and substitution are applied to the original position of the target ground by simultaneous construction of one process. Therefore, the ground improvement is carried out within 24 hours to obtain all the improvement effects. Therefore, the compaction of the ground and the displacement and deformation And so on.;4. Important Uses of the Invention;INDUSTRIAL APPLICABILITY The present invention can be used to prevent the shape change of the clayey soil generated on roads, banks, and construction grounds and to prevent earthquake disasters.
