ANALYSIS OF SHEAR STRENGTH PROPERTIES OF COARSE - GRAINED SOILS IMPROVED BY THE CEMENT (Papers SGEM2018)

M. Sulovska, J. Stacho
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The article deals with determination of shear strength properties of improved coarse - grained soils using a large-dimensional direct shear test apparatus. A road embankment in front of a new bridge over the Danube River in the Komarno city will be made of the gravel improved by the (...)


ANALYSIS OF LOCAL VARIABILITY OF OVERBURDEN PHYSICAL AND MECHANICAL PROPERTIES AS A METHOD FOR ASSESSING KARST HAZARD (Papers SGEM2018)

T.G. Kovaleva, E. V.Drobinina, A. V.Koriakina
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The technique of karst hazard assessment used on the territory of Ust-Kishert village is presented in the paper. We analyse the parameters of the research area natural structure which is characterized by the abundance of carbonate-sulphate karst. In this work, we consider karst rock (...)


ANALYSIS OF NATURAL FREQUENCIES OF THE RECTANGULAR TANK CONSIDERING INTERACTION BETWEEN SUBSOIL AND STRUCTURE (Papers SGEM2018)

L. Uhlirova, N. Jendzelovsky
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Tanks have been presently used for storage of various materials and products. It can be either a loose material, or various liquid and gaseous substances. Tanks have been often used to store the drinking water or various technical liquids, for purposes of waste water treatment, etc. (...)


ANALYSIS OF CAUSES OF UPLIFT ANOMALOUS DEVELOPMENT IN THE SUBSOIL OF THE PALCMANSKA MASA DAM (Papers SGEM2018)

E. Bednarova, J. Skvarka, D. Gramblickova
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Hydraulic structure Palcmanská Maša is located in the eastern part of Slovakia, on the Hnilec River. Its main function is to produce electricity and flood control. It is in operation more than 60 years. The reservoir was created by damming up the river valley by concrete gravity dam. (...)


DETERMINISTIC AND PROBABILISTIC CALCULATION OF A PILE (Papers SGEM2018)

K. Tvrda, L. Prekop
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Pile foundations are among the most widely used deep foundations. Compared to the full-area foundation, here the weight of foundation and extent of excavation works have been reduced while the sheeting and massive backfilling have been eliminated. Concrete piles have been usually made (...)


DIFFERENT VIEW OF NUMERICAL MODELS IN NATM AND ADECO - RS TECHNOLOGIES (Papers SGEM2018)

J. Chabronova, J. Snopko
Thursday 11 October 2018 by Libadmin2018
ABSTRACT In Slovakia, there are two technologies NRTM and ADECO – RS which are currently used for a tunnel excavation. During the tunnel excavation, a disruption of primary balance tension state occurs in a tunnel face followed by spatial redistribution stress, which results in creating a new (...)


ECOLOGICAL ASSESSMENT OF ARTESIAN WATER FROM WELL NEAR VILLAGE OF RASOVO (NW BULGARIA) (Papers SGEM2018)

M. Trayanova, A. Benderev
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Oil and gas exploration in Bulgaria has been mainly conducted in Northern Bulgaria. Up to 2500 boreholes have been drilled on the territory of the country so far with a depth of several hundred meters to more than 6000 m. During drilling, groundwater with different hydrochemical (...)


ECOLOGY AND LONG-TERM SECURITY OF ROAD INFRASTRUCTURE EXPLOITATION (Papers SGEM2018)

N. R.Zhechev
Thursday 11 October 2018 by Libadmin2018
ABSTRACT With climate changes, fortified steep slopes on the road infrastructure are suddenly aggravated by the sudden change in temperature and the rapid melting of accumulated snow. Increased water quantities cause surface and underground flows that turn the slopes into running earth and (...)


EFFECT OF LOAD PLATE SIZE ON RESULTS OF STATIC LOAD TEST (Papers SGEM2018)

M. Decky, M. Pitonak, J. Sramek, M. Hajek, P. Schenk
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The Road materials are exposed during the operation to the effects of traffic loads and climatic influences, in particular changes in air and humidity temperatures, which are reflected by cyclical changes in pavement and subsoil. Strain of different materials is very different its the (...)


EFFECT OF PARTIAL SATURATION ON STRENGTH PROPERTIES OF COHESIVE SOILS (Papers SGEM2018)

M. Wdowska, M. Lipinski, A. Wudzka
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The fundamental element to be ensured during laboratory tests is the control of the boundary conditions in terms of stress, strain and drainage conditions. The determination of the effective stresses is inherently associated with full saturation of soil specimen, as it allows to apply (...)
