Seismic Soil Liquefaction Studies
Earthquake-induced soil liquefaction is considered from the points of view of site evaluation technology, and computer-based analytical developments. In-situ expedient testing procedures are compared with the results of laboratory testing on undisturbed samples. Several types of friction cone penetrometer tests are described, and mechanical cone, electrical cone, and piezometric cone sounding data are compared. Recent developments on analytical effective stress soil models are discussed. Liquefaction behavior is separated into two categories: (1) the inherently unstable situation wherein in-situ stress exceeds residual strength; and (2) the case where accumulation of deformation reaches unacceptable levels. It is suggested that the accumulated deformations category cannot be adequately evaluated using available experimental procedures, but must depend upon effective stress soil model development.
