	1	Design considerations and behavior of reinforced concrete core dams during construction and impounding显示文摘Reinforced concrete core dams can be an alternative solution to conventional dam designs either for permanent impounded reservoirs or flood protection and flood-retaining dams. Dams of this type have been constructed in Austria for various reasons and have shown good behavior during operation. For a better understanding of the load-deformation behavior of this type of dams during construction and impounding, numerical simulations were carried out. The interaction between the thin reinforced concrete core and the dam fill material as well as the influence of fill material properties and other main parameters, such as the roughness of the concrete surface and bedding conditions of the concrete core,on the deformation behavior of dams were examined. The results show that high compressive stress is mainly induced by arching effects in the dam body during construction. During the reservoir impounding, the compressive stresses in the core are reduced significantly while the bending moment in the core footing increases. The results also show that the maximum bending moments occur at the core footing and can be significantly reduced by design improvements. The findings in this study can provide general design recommendations for small dams with a central concrete core as a sealing blanket.

	2	Influence of soft rock-fill material as dam embankment with central bituminous concrete membrane显示文摘This paper demonstrates the difficulties in determining the relevant material parameters for a valuation of the deformation behavior 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 of adjusting 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 has been operated for nearly 20 years and the behavior of the water barrier has been very good.
