Application of Construction Technology of Extruded Concrete Side Wall in Sinanjiang CFRD

The construction technique of extruded concrete side wall is a new method for construction of upstream face slab of CFRD,which was first used during the construction of the Ita rock fill dam in Brazil in 1999.This technique,replacing the processes of bedding materal earth-filling,cutting,refitting,rolling and revetment,which may not only simply construction procrdure,decrease the investment of project,quick up the schedule and enhance and guarantee the quality of construction;but also improve the stress situation of the face and its deformation.
