Key Construction Technologies for High Concrete-faced Rockfill Dams

By referring to the construction technologies adopted in Shuibuya Concrete-faced Rockfill Dam Project and 200m-level high concrete-faced rockfill dams in China, this rticle has presented better construction methods in respect of usage of measures and new workmanships about high-pressure grouting in foundation, dam body deformation control and anti-cracking control of face plate for high concrete-faced rockfill dam, thus provides references for the construction of 200m-level high concrete-faced rockfill dams and obtains rich experiences for construction of 300mlevelhigh concrete-faced rockfill dams.
