Abstract: Solidification of the lake dredged sludge and preventing it from secondary pollution is one of the important aspects of the ecological management of lake at present. The shallow vacuum preloading method used in the reclamation engineering is introduced to solidify the Taihu dredged sludge for the first time. During the solidification process, the surface settlement, vacuum pressure, pore pressure, vane shear strength were monitored and the static load test data were analyzed. The results show that this method is able to consolidate the Taihu dredged sludge quickly and cost effectively.

Key words: Taihu Dredged Sludge, Sludge solidification, Shallow Vacuum Preloading Method, Improvement Effect
