For the duration of glaciations inside the Late Pleistocene, the glacier didn't attain so far as the Czech Republic, and mostly eolian and deluvioeolian sediments deposited , which are predominant in the spot of interest and are represented by loess loam, and reduced percentage of sandy clays and loam and sands of yellow-brown directly and brown to grey-brown colour generally with grey or reddish streaks of predominantly sound consistency and reduced to intermediateSB-3CT plasticity. The Holocene is represented by fluvial sediments of a variable character deposited during the river beds, created up by coarse-grained soils by using a minimum share of fine-grained fraction, which on the flip side takes place in overbank sediments within the kind of flood loams and alluvial cones. Loamy sediments and unsorted fragments are characteristic of deluvial deposits .
3. Dataset and MethodsThe engineering-geological characteristics of soil samples, including their spatial orientation, had been obtained from archive engineering-geological last reviews. Out of the database, compiled selecting needed data in the report texts and appendices, containing 6131 boreholes and 10658 of drawn soil samples and laboratory analyses success, and 7827 of studied samples of an eolian, fluvial, glacial, and deluvial origin (Figure 3) had been selected. The genetic sort is among the database belowattributes which is incorporated during the ultimate reviews based mostly about the geologists' help for the duration of drilling function and their information in the geological setting. Hence, this information and facts can be burdened by an error depending on the individuals' knowledge and professionalism (Figure 2).

European, Czech, and USCS classification system of soils with marked studied samples: (a) the European soil classification process ; (b) the Czech soil classification ...By far the most important evaluated properties are density of strong particles (��n), bulk density (��s), dry density (��d), normal water written content (w), liquid restrict (wL), plastic limit (wP), plasticity index (Ip), consistency index (Ic), porosity (n), saturation degree (Sr), helpful and total cohesion (cef, cu), angle of internal friction (ef, u), and oedometric modulus (Eoed).
Physical-mechanical properties of soils are studied regarding particle dimension distribution, that are represented by basis soil courses according on the classification in ?SN 73 1001 Conventional (Making foundations. Foundation soil under spatial foundations), which can be pretty much like the Unified Soil Classification Method (USCS; ASTM D2487). The basic distinction from the applied foundation soil classifications according towards the stated programs is clear from Figure four, which also depicts the studied samples.
