natural hazards such as earthquakes have threatened the life of human beings during the history.as a consequence, the vibration mitigation of structures has caught great importance. activecontrol of structures is one of the rapidly emerging areas in the concept of structural control. thispaper presents a control method to deal with this subject when the dynamics of the structure ishysteretic an...

The electrical resistivity tomography technique is a geophysical inspection method widely used for several investigations, such as mining exploration, fault localization, groundwater flow, geological and pollution zones. Infusing brine into substructure can increase conductivity becomes useful medium to trace the path of seepage flowing in rockfill dams. In this article, an elapsed-time was dev...

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...

The initial dry density has a significant effect on the mechanical behavior of rockfill material (RFM). size effects minimum/maximum (referred to as density, ρ d ) RFM still need further study. To investigate relationship between and M , series surface vibration compaction tests DEM simulations are performed samples with different maximum particle sizes . Both physical numerical results exhibit...
