Dynamic stability of saturated sand in subsoil beneath dams
When earthquake disturbs stability of saturated sand and sand is compacted or liquefied, it is useful to treat earthquake as vibration; method of determining effects of vibrations on sand was measured using laboratory tests; saturated sand specimen is vibrated in glass cylinder on vibrating table and settlement of surface or liquefaction of sand is measured; results are expressed in dimensionless form using supposition that effects of vibration are strain-dependent; analysis of results gives possibility of evaluating effects of initial density (porosity) of sand, acceleration, depth under surface and volume of sand.
