2008 m. Nr. Priedas Formation of enginnering properties of soils during geological history
A quantitative evaluation of the present behaviour mainly of clay under load is given. The soils examined acquired their present properties in the course of a long and often complex geological history when they attained the state of overconsolidation (non-decompressed to the end). Examined were glaciolacustrine clays, boulder clays, Mio-Pliocene clays and Miocene clays. The results obtained were compared with data for the Eocene London Clays taken from professional literature. Field and laboratory tests permitted to define the basic properties of these soils, the parameters of their “geological history” and stress-strain interdependence. Special attention was given to the effect of exogenic factors on the strength and deformability of the soils. The zonality of the weathering profile was defined.
