Overview of the Quaternary sediments deformation modulus
dependence on testing methodology
The surface of earth on the territory of Lithuania is
covered by sediments of the Quaternary system, which are the object of human
economic activities. Reliable assessment of sediment deformations is an
important task of modern engineering geology and geotechnical engineering. The
deformation of sediments is most often described using the modulus of
deformation. The current article overviews different methods employed in
deformation moduli determination and their application possibilities. The
deformation moduli, which are used in various calculations, are usually
calculated using correlation formulas and empirical coefficients. Thus, the
obtained results may be inaccurate or completely unsuitable for further
interpretation of the numerical situation. This article presents
recommendations with regard to the use of various calculated deformation moduli
in interpreting Lithuanian Quaternary system sediments.
