JOURNAL FREE ACCESSEarthquake response and hydrodynamic pressure on 100m-high concrete face rockfill dams are analyzed by means of an FE-BE method in time domain. According to the results, the earthquake response is readily amplified at higher portion of the dams because of inhomogeneity of the dams, and the hydrodynamic pressure becomes maximum at about 70% of the dam height when reservoir is fully impounded with water. Added mass distribution for earthquake response analysis is newly proposed and validated successfully.View full abstractDownload PDF (3288K) -

JOURNAL FREE ACCESSIt is important to precisely predict the deformations of soft rock foundations for the safety evaluation of a dam body and its foundation at the design stage. Generally, soft rock foundations shows large deformability, and has strain- and stress-dependency in deformability. In this study, parameters of nonlinear deformability were firstly decided by the back calculation based on the results of in-situ plate loading tests conducted for soft rock foundation for an existing embankment dam in the stage of investigation. In order to precisely predict deformation of the foundations due to the fill placement, we made nonlinear deformation analysis using parameters evaluated above. In addition, calculated results were compared with observed distribution of vertical strain in the foundation to verify the accuracy of the analysis. We enthusiastically discussed an appropriate prediction method for the deformation of soft rock foundations due to the fill placement of embankment dams.View full abstractDownload PDF (3161K) -

JOURNAL FREE ACCESSLagrangian Particle Finite Difference Method (LPFDM) is extended to handle rapid and long-traveling flows of soil. LPFDM describes a soil mass as a cluster of Lagrangian material points that move with the material and carry all necessary information, which for each time step is mapped back and forth between the points and a Eulerian grid where the equations of motion are solved.View full abstractDownload PDF (2493K) -
