Variant Methods of Determinating Biogenic Grounds Deformation Behavior

ABSTRACT

The issues of biogenic grounds (containing organic residues) deformation behavior determination using various methods are shown in the article. Deformation behavior is considered to be the basic property while estimating the settlements of these grounds (modulus of deformation E, modulus of elasticity E_y, relative compressibility λ, consolidation coefficient С_к etc.). The shown methods of defining the settlements are complex that is they are based on direct testing (stamps, compressive tests), quiescent probing, seismic sounding and physical characteristics of the grounds, that gives the possibility of getting reliable and accurate effect. Guidelines on hardening soft grounds are given.
