Abstract:
Monit or ing the embankment deformation and its var iatio n law is very impo rtant for t he building embankment w ith the slurr y filled geot ex tile tubes. Thr ee ty pes of co nstr uction methods w ere desig ned for the building embankment, including natural dr ainage, v acuum prelo ading dra inag e, and adding curing ag ent . The advantag es and disadvantag es of the t hr ee methods wer e summar ized thro ug h the mo nitor ing the var iatio ns of tube height and w idt h. Results showed that the var iation of tube heig ht is co nsistent w ith the co nso lidatio n law o f the slurr y in the tube, and it is also related t o the pro per ties o f filling slur ry , the t ype and do sag e of curing agent, and dr ainage w ay. Mor eo ver , the vo lume reduction consolidat ion method can be used to pr edict the height of embankment after its completio n.
