Thickness of overburden and overconsolidation of Brno Clay
Pavlová, Martina ; Boháč, Jan (advisor) ; Mašín, David (referee)
Knowledge of the thickness of the overburden of sediments is important in tackling different geological and geotechnical issues. This Bachelor Thesis deals with the available methods for determining the original overburden thickness and with the possible errors from the point of view of the soil mechanics. The area of interest is the northern part of the Vienna Basin, in the vicinity of the town of Brno. The sediments in question are Miocene clays, known locally as Brno Tegel. Consequently the Thesis includes also a brief description of the geological origin of the Carpathian Foredeep.

Secondary compression of Brno Tegel
Pavlová, Martina ; Boháč, Jan (advisor) ; Král, Jan (referee) ; Rozsypal, Alexandr (referee)
Observation and measurement of long-term volumetric deformation of clay are important in tackling different geotechnical and geological issues. The area of interest is the northern part of Vienna Basin, where Miocene clays sedimented. It is locally known as Brno Tegel. The Thesis deals with the secondary compression of clays, which can be defined by the Cα/Cc concept. The one-dimensional creep can be determined using the numerical values of the coefficient of secondary compression Cα and subsequently the thickness of overburden of sediments can be estimated. The two different theories, known as Hypothesis A and B are also discussed, which have been used to interpret the effect of creep during the primary consolidation phase. The laboratory measurements of long-term oedometric tests are presented for two undisturbed samples and one reconstituted sample of Brno clay. A nonstandard behaviour in uniaxial creep is also discussed, namely the observed diffusion collapse. Powered by TCPDF (www.tcpdf.org)
