Influence of soft rock-fill material as dam embankment with central bituminous concrete membrane

Peter TSCHERNUTTER

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 1, Pages 63-70 doi: 10.1007/s11709-010-0016-3

Abstract: shell by means of an embankment dam of medium height.Laboratory as well as field tests on solid rock-fill material were performed before the beginning ofDuring the construction the properties of the available rock-fill changed from solid to soft materialsThis gave rise to the necessity of adjusting the dam design of the downstream dam shoulder.and downstream dam shell were observed during construction and operation.
