this paper studies thoroughly and deeply the results of about one hundred triaxial compression tests on thirty types of rockfill materials. the materials are categorized in accordance with their particles shape (angular / rounded) and gradation characteristics. the main tool of the study is the hyperbolic model developed by duncan and chang. the focus of the study is on the variations of deform...

There are increasing demands from dam safety regulations and guidelines to upgrade the rockfill dams, especially in Norway where over 180 large dams present. To protect hydraulic structure against overtopping events or leakages, it is important use defence mechanisms such as a protective layer of riprap on downstream slope. In this article, we display 9 experimental setups riprap, conducted at ...

Rockfill dams are accounted as useful measures in watershed management projects. How-ever, the sediment transport through the rockfill materials, could impact their lifetime duration. Previously, researches have been conducted to describe the various hydraulically issues of the flow passing through these structures However; there is no general relationship to estimate the sediment transport rat...

In order to safely and efficiently use soft rock aggregate cemented dams in red bed regions promote the development of widely sourced sand gravel dam materials, Jinjigou project China applied for first time construction material dams. This article further explores concept from conducting on-site direct shear tests research on ratios invents a new structure method by combining with rockfill. als...
