The objective of the present invention is to provide a dredged soil stabilization method using eco-friendly solidification. The eco-friendly solidification comprises : 30-100 parts by weight of TDF cinder; 10-100 parts by weight of slag; 10-80 parts by weight of petroleum cokes desulfurized gypsum based on 100 parts by weight of high calcium cinder. The present invention omits drying and curing processes and induces high absorption and internal heat generation so that the dredged soil can be efficiently and environmentally-friendly solidified. Specially, the present invention uses high calcium cinder as a main material, utilizes the TDF cinder, slag fine powder, and petroleum cokes desulfurized gypsum as stimulants so that the dredged soil can be used for treating economical construction materials or poor subsoil with enhanced physical properties. In addition, the present invention recycles the dredged soil and contributes to environmental protection.
