Dynamic analysis demonstrates the limitations of homogeneous soil models in earth dam systems, highlighting the mechanical influence of pore water during earthquakes.
Key Points
To assess the dynamic response of earth dam-reservoir systems while addressing the mechanical role of pore fluid within saturated granular soil structures.
Evaluated dynamic response modeling approaches that treat soil as a two-phase granular solid skeleton saturated with water versus conventional single-phase homogeneous solids.
Conventional models that simplify soils into equivalent homogeneous solids neglect the dynamic effects of pore water on soil mechanical behavior.
Accounting for the multi-phase nature of saturated granular soils is necessary to prevent underestimating deformation and instability in dam-reservoir systems during seismic events.
