Abstract

Abstract The Oligocene Kiscell Clay is a widespread sediment of the Budapest region. The best-evaluated parts of the deposit are found along the new Metro (subway) line (Line 4) on the Buda side of the Danube River, where cores were cut. The geomechanical parameters of the Kiscell Clay were studied and evaluated using 481 samples from 41 cores. Nearly 5000 data were processed using different statistical parameters. The results of the statistical analyses are compared with previously-described soil-mechanical parameters; regional correlations of the mechanical properties of the Kiscell Clay are made by comparison with the results of previous analyses (Görög 2007a). There are significant discrepancies in the datasets of cohesion and uniaxial compressive strength, but other parameters show better correlation. In any case these analyses provide information for the engineering geologic design and planning for underground structures.
