Abstract:A case study of applying the preloading technique to treat  hydraulic reclamation of Dayaowan Port area of Dalian is reported. The technical problems related to the stepped loading design, construction and monitoring are discussed. Through the  analysis on the monitored data, variations of ground settlement and deep settlement with time are displayed and the interrelation among the step of preloading, the height of preloading and consolidation time are examined.
Keywords:soft soils; preloading; ground settlement;deep settlement; consolidation; step loading
