This research presents the impact of base fixity on seismic analysis including soil-structure interaction (SSI) considering linear and nonlinear soil-foundation interface conditions. A set of inelastic time history analyses using a yielding singledegree-of-freedom structural system with different fixity conditions at the base are used. The base fixity configurations considered are: 1) fixed-bas...
upstream blankets, drains and cutoff walls are considered as effective measures to reduce seepage, uplift pressure and exit gradient under the foundation of hydraulic structures. to investigate the effectiveness of these measures, individually or in accordance with others, a large number of experiments were carried out on a laboratory model. to extend the investigation for unlimited arrangement...
The design of relief wells includes determination of the distance of relief wells from each other, their distance from the dam upstream, the well diameter and discharge into each wells. This study tends to investigate these factors effect on uplift pressure in earth dams. For this purpose, finite elements method (FEM) was used for different configuration of relief wells in downstream of an eart...
