Deformation mechanism in the core rockfill dams with heavy load and high-stress level is difficult to predict control, which one of key problems be solved dam operation safety management control. Aiming at large error obtained by parameter-based functional models (regression model, grey theory etc.) deformation prediction dams, a fractal method its technical process combining variable dimension...

Dams are one of the most important water structures built to meet vital needs people such as irrigation and energy. It is great importance examine seismic safety dams. In addition, it investigate interaction behavior dams due bodies dams, reservoir water, foundation being in constant interaction. Therefore, this study, clay core rockfill (CCR) investigated by considering dam-foundation-reservoi...

A procedure is presented for simulating the sequential impoundment process of concrete-faced rockfill dam using nonlinear finite element method. The parameters of constitutive relationship of stress and strain are determined by tri-dimensional compression test in laboratory. The model applied in this study adopts the technique of element birth and death to simulate the sequential impoundment pr...

This paper presents the results of an extensive laboratory set tests aimed to study failure downstream shoulder highly permeable rockfill subjected overflow. The experimental research comprised testing 114 physical models by varying following elements: (i) median size uniform gravels (7 45 mm); (ii) configuration dam, i.e., upstream and shoulders crest or just shoulder; (iii) dam height (from 0...
