Influence of soft rock-fill material as dam embankment with a central bituminous concrete membrane
This report demonstrates the difficulties in determining the relevant material parameters for a valuation of the deformation behaviour of the up- and downstream dam 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 of construction. During the construction the properties of the available rock-fill changed from solid to soft materials. This gave rise to the necessity to adjust the dam design of the downstream dam shoulder. Several times higher dam settlements as well as significant differential settlements between the up- and downstream dam shell were observed during construction and operation. Apart from this situation, the dam is being operated for nearly 20 years and the behaviour of the water barrier has been very good.
