SUMMARY
In the course of engineering-geological works connec-ted with a certain investment undertaking, I.e., the con-struction of "lazienkowska" bridge route in Warsaw, a large number of laboratory determinatlons of physico-mechanical soil properties were made. On the whole, about 1,000 samples of soils were taken. About 3S0 detailed analyses were performed under laboratory conditions and In accordance with 'the provisions ,of actual Polish norms, being made of the equipment of the Geotechnical Labora-tory of the Warsaw Offices of Land- and Aerial Transport Studies and Designing, produced by the research instru-mentation works in Cracow. A vast amount bf laboratory determinatlons enabled to find interdependences between lithology and genesis of soils, on the one hand, and their physico-mechanical parameters on the other hand. It fol-lows from the lithostratigraphical profile obtained
(cf.
przeg. geol., No. 2-1972) that 6 basic genetic groups may be distinguished In the soil substratum of the bridge route. These groups may be further divided into lithological sub-groups, and these - into elementary units, In accordance with the classification scheme of the Polish Norm PN-S4/B--02480. In the present paper, 3 genetic groups of soils, I.e., cohesive clays, boulder clays, and stagnant lake clays are characterized.PE3toME
