20.500.12556/DKUM-70525 The degree of deterioration of the tunnels of the Prague Metro based on a monitoring assessment Stopnja propadanja tunelov praškega metroja, ki temelji na oceni monitoringa Understanding the ageing of structures is a very important issue from the point of view of assessing the risk inherent in those structures. Geotechnical structures, of course, have their own specific risks. This paper is focused on the tunnels of the Prague Metro, looked at from various aspects, i.e., geology, construction systems, and the influence of flooding. The section of the tunnels that was selected for monitoring is one of the most affected, and has a large system of cracked segments. However, even for this affected section the monitoring systems, based on macro- and micro-approaches, showed no significant deterioration was taking place. Nevertheless, for long-term monitoring a wireless system for data collection and transfer was installed and implemented. The results so far have been very positive. Razumevanje staranja objektov je z vidika ocene rizika teh objektov zelo pomembno. Geotehnični objekti imajo glede tega svoje posebnosti. Prispevek se osredotoča na tunele v praškem metroju z različnih vidikov – geologije, konstrukcijskih sistemov in vpliva poplavljanja. Izbrano mesto za izvedbo monitoringa predora je bilo eno najbolj prizadetih z velikim sistemom razpok. Monitoring tega mesta, ki je temeljil na makro in mikro pristopih, ni kazal posebnega propadanja. Vseeno je bil za kontrolo v daljšem časovnem obdobju nameščen in uporabljen brezžični sistem za zbiranje in prenašanje podatkov. Dosedanji rezultati tega monitorninga so pozitivni. tunnel metro deterioration ageing geology construction monitoring assessment MEMS geophysical wireless data transfer metro flooding geotehnika predori podzemne železnice propadanje Praga monitoring tunel metro staranje geologija konstrukcija kontrolno preverjanje MEMS geofizikalno brezžični prenos podatkov poplavljanje v metroju true false true Angleški jezik Slovenski jezik Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru Znanstveno delo 2018-05-18 10:25:39 2018-05-18 10:26:28 2022-08-01 19:27:14 2019-07-11 18:10:13 2007 0 0 str. 34-47 št. 2 Letn. 4 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1854-0171 624.13 215987712 246147072 1854-0171 URN:SI:UM:DK:4R3BJF1Q Acta_geotechnica_Slovenica_2007_Vanicek,_Vanicek_The_degree_of_deterioration_of_the_tunnels_of_the_Prague_Metro_based_on_a_monitoring_as.pdf Acta_geotechnica_Slovenica_2007_Vanicek,_Vanicek_The_degree_of_deterioration_of_the_tunnels_of_the_Prague_Metro_based_on_a_monitoring_as.pdf 1 80C2C8515378C52AC5ECCADA2385AE8C 75c20bc494b3e3f27cd7772120e30ffe1f2530913e95aded2bf0656ca9f6dd8c f7c493e8-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/8d76e642-2965-4192-8856-6be32e2831ad https://dk.um.si/Dokument.php?lang=slv&id=124842 http://fgserver3.fg.um.si/journal-ags/2007-2/article-3.asp 1 https://dk.um.si/Dokument.php?lang=slv&id=124843 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Acta geotechnica Slovenica 0 0 0
