The achievements of deformation control in dam body and cracks on concrete face slab are tremendous owing to the completion or under construction of some 200 m high concrete face rockfill dams(CFRD) since 2000.A series of effective measures such design techniques as the rock selection of dam materials
porosity control
the zoning of dam section
crack prevention of concrete face slab and plinth
and the construction techniques such as compacted equipment selection
dam settlement control in advance
stage construction are adopted
which gains achievements of less deformation of dam body and less crack of face slab.Herein
some tentative plans and research subjects for 300 m super-high CFRD construction technique are proposed.
