An analysis of stress-strain behaviour and wetting effects on quarried rock shells
The analysis of stressstrain behaviour and the effects of submergence on quarried rock shells, used mainly in dams but also in road construction, is of major importance from both economic and safe...
Finite Element Analyses of Stresses and Movements in Embankments During Construction.
Abstract : The objective of this investigation was to develop procedures for conducting finite element analyses of stresses and movements in embankments during construction. The procedures developed involve incremental analyses, simulating successive stages during construction of the embankment, and employ nonlinear stress-strain parameters determined from the results of laboratory tests. Previous studies of the nonlinear, stress-dependent stress-strain behavior of soils were extended during this investigation to include variations of Poisson's ratio values as well as modulus values for use in incremental analyses. In order to examine the suitability of these procedures for representing the stress-strain characteristics of a wide variety of soils under both drained and undrained test conditions, the procedures were applied to 46 different soils, ranging from cobble sizes to highly plastic clays, for which stress-strain information had been published or was available from other sources. In each case it was found that the simple procedures developed for representing nonlinear, stress-dependent soil stress-strain behavior were convenient and provided reasonably accurate representations of the actual soil behavior.

Foz do Areia Dam—Design, Construction, and Behaviour
The 525 ft (160 m) high Foz do Areia dam in the Iguacu River, Parana, Brazil, built by 'Companhia Paranaense de Energia - COPEL', between 1975-1980, is part of the 2500 MW 'Governador Bento Munhoz da Rocha Netto' powerplant. The main features of its design and construction are described and commented. Updated figures concerning its 4. 5-year performance up to February 1985 are given and demonstrate the excellent behavior of the rockfill dam.
