<p>Filters in embaknment dams are composed of specifically-designed entities (zones) of coarser-grained soils placed at specifically-targeted locations within or adjacent to the dam structure. Filters are designed and constructed to achieve specific goals ...

<p>The paper provides an outline of important points that need to be recognized and understood when selecting material for use in embankment dams. It covers soil materials; rockfill materials; granular filters and drains; asphalt concrete as a water barrier; ...

<p>purely deterministic approach in geotechnical engineering usually is chosen despite there is enough knowledge about the uncertainties and spatial variability of the soil parameters. The geotechnical design and recommendations are based on some field observations, ...

Nam Ngum 2 dam, a large concrete face rockfill dam (CFRD) of 182 m height, is under construction and impounding is scheduled to start at beginning of April 2010. The dam is situated in a narrow valley and founded on sedimentary rock of variable strength. Dam ...

In the last 25 years, following the completion of the Willow Creek ‘all’ RCC dam, the experience and knowledge gained through the completion of over 350 RCC dams has been considerable. Many new ideas and innovations have been tested and adopted so that today ...

<p>One of the most common measurements used for quality control of earthfill placement is compacted density. The use of density testing for the control of fill placement and as a key indicator that material placed will meet specified parameters has broad application ...

<p>The purpose of this manual is to provide information and guidance on the use of rollercompacted concrete (RCC) in dams and other civil works structures. Elements discussed includeinvestigation and selection of materials, mixture proportioning, material ...

This laboratory mechanical property investigation of roller-compacted concrete cores from Elk Creek Dam was conducted by the U.S. Army Engineer Waterways Experiment Station (WES) for Headquarters, U.S. Army Corps of Engineers (HQUSACE), under the Earthquake ...

<p>Coal mining processes result in two general types of by-products: coarse coal refuse (CCR), a mixture of soil and rock commonly used to construct an impoundment coal refuse dam or embankment, and fine coal refuse (FCR) slurry, a mixture of soil, rock dust, ...
