<p>The dynamic properties of plastic concrete used as an alternative core in embankment dams were studied. To investigate the specimen&rsquo;s dynamic properties, an extensive series of monotonic and cyclic triaxial tests were done. Bentonite contents 5.5%, ...

<p>The original design of a dam may be reevaluated for a number of reasons, including the occurence of an incident or unusual load, the availability of new information, the refinement of certain design requirements or guidelines, the adoption of risk-based ...

<p>Scour of rock is a complex process and can be very problematic for dams when excessive scour threatens dam stability. Removal of individual rock blocks is one of the principal mechanisms by which scour can occur, particularly in unlined spillways and on ...

The paper also discusses appropriate safety factors and implications of various modeling assumptions to the design of levees. Factors such as assumed depth of desiccation, involvement of foundation soils in the model, and others are examined and summarized. ...

<p>Designers of roller-compacted concrete (RCC) dams are invariably concerned with control of thermal-induced tensile stresses and thus the possibility of uncontrolled cracking which can lead to leakage related problems in the dam. Complex computer generated ...

This report compares two different dam types (Roller Compacted Concrete Dam and Concrete Face Rock-fill Dam) in order to help the decision making when choosing what dam type to build in Panama, where Vattenfall is involved in a joint venture to build a dam ...

Beach City Dam is one of sixteen flood control projects located in the Muskingum Watershed. The Huntington District, U.S. Army Corps of Engineers was tasked to model a dam failure for Beach City Dam and provide water surface profiles and inundation mapping ...

Shortly after construction, a bulge developed in the asphalt liner adjacent to the intake structure. The bulge cracked the upper asphalt layer in 1974, activating the dike drain pumps. Investigations of the bulge area found excessive hydrostatic pressures ...

An LSDYNA model of the control structure was developed for evaluation, design, and verification of several components. Two water surfaces were modeled, one representing the PMF and the other the maximum normal pool the latter was combined with two operational ...

The shear strength of bonded lift joints and shear keys is important to overall dam stability during an earthquake but it is poorly understood. This paper provides a brief review of shear strength data from recent testing and available literature to estimate ...
