ABSTRACT

The present paper presents an analysis of methods for measurements of soil deformation parameters, i.e. E1, E2, Evd, I0, Is determined using the VSS plate method compared with the use of the LFG (LWD) dynamic plate method. The study addresses a correlation between measured soil properties (using VSS and LFG (LWD) methods). It is noted that a cautious approach is required when the dynamic modulus E vd is compared to the deformation index I0 and the compaction index Is , which follows from static relationships determined according to the VSS method.
