Of particular interest is the fact that opening of fractures on the upstream side of dams, which have been observed in reality, can be predicted. 1...

... SUMMARY: This report describes practical design methods for dam foundations on rock. The practical aspect is fundamental since only those methods actually used by designers that have been tried and tested in practice offer any real utility. Although well known, the limit equilibrium method...
