The typical reclaimed sample land is tested and analyzed form many aspects,and discovered the laws of soil compaction for typical reclamation techniques are discovered.The soil compaction models for different reclamation techniques are established,in the meanwhile,the spatial analysis of soil compaction is processed.With the increasing of soil depth,the soil compaction of un-reclaimed land appears trend of increasing gradually,but the soil compaction of the land reclaimed by use of hydraulic dredge pump decreases nonlinearly in vertical,and the of the soil compaction of the land reclaimed by use of towed scraper has unobvious variation.There are significant difference of soil compaction among the land reclaimed by use of hydraulic dredge pump,the land reclaimed by use of towed scraper and the un-reclaimed land.
