Technical paper: Constructional deformations in a rockfill dam

A D M Penman, DSC, CEng, FICE and J A Charles, MSc(Eng), ACGI, CEng, MICE. This paper was first published in GE’s March 1973 edition.

The movements which have occurred in the downstream rockfill shoulder of Llyn Brianne Dam during construction are described and then compared with those calculated from an analysis using a finite element technique, with parameters derived from the results of large-scale laboratory tests on samples of the rockfill.
