NUMERICAL ANALYSIS OF DEWATERING PROCESS OF DEEP EXCAVATION (Papers SGEM2018)

G. Wrzesinski, J. Kowalski, A. Miszkowska
Thursday 11 October 2018 by Libadmin2018
ABSTRACT At present many new housing projects are being realized in Poland. They are often built in areas characterized by complex hydrogeological and geotechnical conditions. In such cases, the need to build deep excavations is complicated, especially when there is a high water table. The (...)


NUMERICAL ANALYSIS OF THE BEHAVIOUR OF A FLEXIBLE PILE FOUNDATION VERSUS A RIGID ONE UNDER LATERAL CYCLIC ACTION (Papers SGEM2018)

L. BATALI, A. DRAGUSIN, H. POPA
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The purpose of the present paper is to analyse the behaviour of a flexible pile foundation versus a rigid one when submitted to lateral cyclic action coming from waves or wind, through numerical modelling using 3D finite elements. The comparison elements are: the maximum pile head (...)


ONE OF THE GEOTECHNICAL TECHNOLOGIES TO STRENGTHEN THE FOUNDATION BASE IN CONSTRAINT ENVIRONMENT IN THE ADDITION OF 4 FLOORS (Papers SGEM2018)

N. Sokolov
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Electric discharge technology (EDT) has ample opportunities in the field of geotechnical construction. It has a number of technological advantages. EDT bored piles have increased bearing capacity both for the soil and for the material due to the maximum inclusion of the surrounding (...)


PARTIAL REPLACEMENT OF NATURAL SAND BY GRANULATED BLAST FURNACE SLAG (GBFS) IN FINE AGGREGATE FOR CONCRETE: PRACTICAL APPLICATION IN VIETNAM (Papers SGEM2018)

T.N.Nguyen, V.V.Nguyen
Thursday 11 October 2018 by Libadmin2018
ABSTRACT: Natural sand resources in Vietnam have been nearly exhausted and its price has been increasingly escalating. According to estimation, by 2020 Vietnam will not be able to provide enough sand for construction industry. Alternative materials for natural sand are now encouraged by the (...)


PERMAFROST AND FROST MOUNDS OF THE OKINSKOE PLATEAU (EASTERN SAYAN RIDGE), RUSSIA (Papers SGEM2018)

S.V. Alexeev, L.P. Alexeeva, E.A. Kozyreva, Yu.K. Vasilchuk, A.A. Svetlakov
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Research has been conducted on the permafrost in the Sentsa River valley for the first time. The investigated units of the permafrost are cryogenic structures of unconsolidated deposits and active layer temperature, morphology and cross-section of sizable frost mounds and chemical (...)


PERMEABLE REACTIVE BARRIERS IN DEEP MINING (Papers SGEM2018)

A. Tokarz, J. Grabowski, D. Nowak
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The technology of Permeable Reactive Barriers in recent years is one of the most frequently developed methods of protecting the soil and water environment from pollution. These are zones filled with reactive material, in which during the flow of contaminated groundwater, contaminants (...)


POSSIBILITIES OF USING LIGHT DYNAMIC PENETRATION IN THE LANDSLIDE AREA (Papers SGEM2018)

T. Siroky, O. Molinek, T. Kral, P. Lazorisak, M. Janega
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The authors of this article describe the suitability of using light dynamic penetration in the target area. The area of this survey was selected on the already reclaimed area, which, however, proved to be unstable. The main objective was to locate individual water-saturated horizons (...)


POSSIBILITIES OF USING HEAT PUMPS IN SLOVAKIA ON THE BASIS OF ASSESSMENT OF THE QUALITY AND QUANTITY OF GROUNDWATER (Papers SGEM2018)

L. Gabaniova, M. V. Kmecova, Z. Simkova, K. Kubacki, K. Horansky
Thursday 11 October 2018 by Libadmin2018
ABSTRACT When it comes to efficient use of water, especially groundwater, a water / water heat pump is a very good example of its high efficiency at the optimal qualitative and quantitative conditions of the groundwater used. Hydrological and hydrogeological conditions on the territory of (...)


PRACTICAL ASPECTS REGARDING THE BEHAVIOUR OF SENSITIVE AND SOFT PLASTIC CLAYS IN ENGINEERING WORKS (Papers SGEM2018)

M. Sebastian, A. Chirica
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Lately, in our country, the necessity of expanding the transport infrastructure works has led to the necessity of designing and executing engineering constructions in areas with lands considered difficult in terms of physical and mechanical characteristics. According to the Romanian (...)


PREDICTION OF HIGH-RISE BUILDING SETTLEMENT FOUNDED IN NEOGENE CLAY (Papers SGEM2018)

Z. Gallikova
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The article deals with the prediction of deformation progress of the basement for a high-rise building founded in a deep foundation pit of 12.0 m below the ground level. Foundation consists of a stiff reinforcement concrete raft with basement in a Neogene layer of several ten metres. (...)
