Assessment of the Landfill Barrier System through Numerical Analysis: Rehabilitation and Expansion of Belgrade Landfill Case Study
(MDPI, 2022-06-23)There are still many unmanaged landfills around the world that pose significant potential envi-ronmental problems. One of the largest unmanaged landfills in Europe, which has been used for more than 40 years to deposit ... -
The Reinforcement of Sand by Fibres with a Non-Uniform Shape
(SCIENDO, 2021-06-12)The reinforcement of soil is used to improve its strength and stiffness. The standard method of soil reinforcement is an application of geosynthetics. Soil reinforcement by distributed discrete fibres represents an alternative ... -
Remediation of a railway embankment using geocells and deep soil mixing - a numerical analysis
(Czech Technical University in Prague, 2022-01-19)Progressive settlement of the embankment under the railway track near Ždár nad Sázavou, the Czech Republic, has been observed for many years. Immediate improvement was needed to secure the safety of the traffic and to ... -
Upper Cretaceous to Pleistocene melilitic volcanic rocks of the Bohemian Massif: petrology and mineral chemistry
(Slovak Academy of Sciences, 2015-06-15)Upper Cretaceous to Pleistocene volcanic rocks of the Bohemian Massif represent the easternmost part of the Central European Volcanic Province. These alkaline volcanic series include rare melilitic rocks occurring as dykes, ... -
Numerical Modelling of Slope Instability
(Elsevier, 2015-11-07)This article is dealing with stability of the highway cut in Eastern Slovakia. The cut is situated in rock environment of the Carpathian flysch, which in area of the cut mostly consists of shale with different degree of ... -
Boron isotopic variations in tourmaline from metacarbonates and associated calc-silicate rocks from the Bohemian Massif: Constraints on boron recycling in the Variscan orogen
(China University of Geosciences, 2021-01-11)Various metacarbonate and associated calc-silicate rocks form minor but genetically significant components of the lithological units in the Bohemian Massif of the Variscan orogen in Central Europe. These rocks vary in terms ... -
Grouting below Subterranean Water: Erosional Stability Test
(MDPI, 2021-04-30)The article is focused on the medium-term negative effect of groundwater on the underground grout elements. This is the physical–mechanical effect of groundwater, which is known as erosion. We conduct a laboratory verification ... -
Energy-Pile Model Verification
(KGH, 2020-12-31)Equipping the foundation piles with a liquid circuit pipeline makes it possible to use the advantageous thermal capacity of the soil for heating and cooling buildings at low cost. The energy performance of the energy-pile ... -
Reinforcing of Sand With 3D Printed Fibres – Review of Properties, Fabrication of Fibres and Initial Testing Programme
(IOP Publishing, 2020-12-09)Fibre reinforcement is an effective method of soil improvement that presents an alternative solution to other more common methods of ground reinforcement such as mechanical stabilization by geosynthetics (geogrids, ... -
Geochemistry and Sr–Nd–Pb isotope characteristics of Miocene basalt–trachyte rock association in transitional zone between the Outer Western Carpathians and Bohemian Massif
(Earth Science Institute, Slovak Academy of Sciences, 2020-10-29)Representative samples covering all petrographic types of the Miocene subvolcanic (dykes and sills) basalt– trachyte rock association from the Uherský Brod area (UB, Moravia) in the Czech Republic were studied. The UB area ... -
(40)A/Ar-39 step-heating dating of phlogopite and kaersutite megacrysts from the Zelezna hurka (Eisenbuhl) Pleistocene scoria cone, Czech Republic
(Earth Science Institute, Slovak Academy of Sciences, 2020-08-15)(40)A/Ar-39 step-heating of mica and amphibole megacrysts from hauyne-bearing olivine melilitite scoria/tephra from the Zelezna hurka yielded a 435 +/- 108 ka isotope correlation age for phlogopite and a more imprecise ... -
Assessment of empirical formulae for determining the hydraulic conductivity of glass beads
(De Gruyter Open, 2018-08-14)Empirical formulae are often used in practice to quickly and cheaply determine the hydraulic conductivity of soil. Numerous relations based on dimensional analysis and experimental measurements have been published for the ... -
An Evaluation of the Mathematical Models of Energy Piles
(Sciendo, 2020-04-03)A current trend is to reduce the energy performance of buildings by using alternative sources for heating and cooling. One of the most promising, and so far unprecedented sources of heating and cooling, is the use of energy ... -
Lead isotope evolution of the Central European upper mantle: Constraints from the Bohemian Massif
(CHINA UNIV GEOSCIENCES, BEIJING, 2020-05-15)The Pb isotope composition of the upper mantle beneath Central Europe is heterogeneous due to the subduction of regionally contrasting material during the Variscan and Alpine orogenies. Late Variscan to Cenozoic mantle-derived ... -
