LONG-TERM SETTLEMENT PREVENTION METHOD OF SOFT GROUND AND LONG-TERM SETTLEMENT DETERMINING METHOD OF SOFT GROUND

摘要

PROBLEM TO BE SOLVED: To provide a long-term settlement prevention method of the soft ground, capable of inexpensively and surely preventing settlement over a long period by simple construction. SOLUTION: This long-term settlement prevention method of the soft ground is formed by laying banking 13 on the viscous ground 10 of developing a structure like natural sedimentation clay. Before laying the banking 13 on the viscous ground 10, a plurality of columnar vertical sand piles 11 are driven in the viscous ground 10, and the structure of the viscous ground 10 is positioned lower by forcibly pushing-in by compaction of sand when driving these respective sand piles 11, to approach to remolded soil 10'.
