A study of optimal construction scheme of high concrete face rockfill dam in consideration of rockfill creep effect
Optimal construction scheme of high concrete face rockfill dam(CFRD) is studied taking into account creep deformation of rockfill. The results show that creep characteristic of rockfill influence on deformation of dam bedding node under different construction schemes. The zone by zone character of various materials of a rockfill dam decides objectively the necessary existence of an optimal scheme for the construction of filling ascension works. The maximum normal displacement of the facial slab is small in the filling. Scheme where the rock-filling body ascends uniformly and its distribution along the slab slope is also rather uniform
which is favourable to the harmony between the deformations of slab and pad layer beneath it. From the view of the majorized filling scheme
it is suggested that the rolling and compacting construction procedure producing uniform ascension of filling shall be used for high rockfill dams.
