In order to reclaim the dredged soil stockyards as soon as possible,in-site tests as well as field and experimental investigations on three reclaimed yards on the Eastern Route of the South-to-North Water Diversion Project are reported in this paper,due to the deficiency of land resources.The results show that: the methods of river dredging,soil features of dredged soil,and completion time are three important factors that influence the engineering properties of the stockyards;the hydraulic sorting effect of cutter suction construction is significant,and the elevation and strength of the stockyards decrease gradually with the distance to the location of filling-mouth;dredged soil with higher clay particle content has lower permeability and has more difficulties in consolidating under natural conditions;and surface drainage leads to the rapid formation of a stiff shell layer,and is also beneficial to the reclamation use of the stockyards.
