Collapse potential and ultrasonic pulse velocity of loess soils after treatment with expanded perlite and metakaolin
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)Collapsible soils, including loess, can support heavy loads at their natural humidity but then collapse rapidly and lose a substantial volume when the humidity increases. Soil collapse potential at different immersion ... -
Considerations on an embedded pile’s effective length in an analytical calculation according to the commentary on the STN 73 1002 standard
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)The analytical model for calculating the bearing capacity of a pile, presented in the commentary to STN 73 1002 – Pile Foundations, gives a recommendation to reduce the pile’s length in the calculation of the shaft resistance. ... -
Directing classical geotechnical engineering to future challenges
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)Geotechnical engineers have traditionally been focused on soil mechanics, rock mechanics and engineering geology. Thus it has been sufficient to master these topics to be recognized as a key participant in building and ... -
Earth structures – a summary of the last 50 years
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)This paper discusses changes and developments in the field of Earth Structures that have been presented and discussed over the last fifty years at the annual national conferences on Foundation Engineering held (with foreign ... -
Evaluation of deformation and strength parameters of organic soils for the design of geotechnical structures
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)The evaluation of deformation and strength parameters of Holocene organic soils obtained from DMT dilatometer tests based on empirical relationships and ANN Artificial Neural Networks is presented. The evaluation of undrained ... -
Geophysics for underground engineering
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)The growth of underground engineering brought a need for the use of geophysical methods for research of underground constructions rather different in approach compared to that of civil engineering. These changes relate to ... -
Long-term experience of the thermo-active ground source system at the metro station Taborstrasse in Vienna
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)Four of the stations newly opened during the underground extension of the U2 line in Vienna in 2008 have been covering a large part of their heating and cooling needs for now almost one and a half decades by using geothermal ... -
Possibilities of complex numerical modelling at the Czech Geotechnical Society workplace
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)In the paper, there are examples of complex geotechnical problems in both 2D and 3D that are modelled using PLAXIS software on the specialist workstation provided by the Czech Geotechnical Society to their members. -
Providing stability to a highway cut in a landslide area with the use of diaphragm wall panels
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)The route of the D1 highway in the Lietavská Lúčka - Dubná Skala section near Žilina is taken forward by a 17 m deep cut in a section about 300 m long. The first proposed solution of the highway route was based on the ... -
Quality improvement by application of a revised standard – feasibility studies on 2500 soundings
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)CPT is a geotechnical investigation method that, depending on the geology, has been proved to be an essential tool to establish the Geotechnical Design Model. However, doubt has been raised about the quality of the data. ...
