Abstract : The primary objective of this research was to develop analytical procedures which may be used to analyze the effects of reservoir filling on the stresses and movements in earth and rockfill dams. This study also includes a review of the behavior of embankments during reservoir filling, and an experimental investigation of the effects of water on the properties of granular materials. When movements develop in dams and foundations, cracking and consequent erosion and failures have been observed in a number of dams. One of the major factors contributing to the development of differential movements during reservoir filling is the compression due to wetting which occurs in a wide variety of different types of soils. Procedures developed to analyze the effects of wetting were incorporated in a plane strain finite element computer program, which is also capable of representing other effects of water such as seepage and buoyant loads for soil masses with arbitrary shapes and boundary conditions.
