Influence of mould suction on the volume - change behaviour of compacted soils during inundationMaček, Matej (Avtor) Majes, Bojan (Avtor) Petkovšek, Ana (Avtor) , Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru (Lastnik avtorskih pravic) oedometer testssuctionswellingcollapseAfter construction, compacted clayey soils in different earth structures equilibrate their water content and suction with the local environment. In wet climatic conditions the compaction on the dry side of the Proctor curve, which enables a high layer stiffness during construction, may result in permanent deformation and softening during the lifetime of the structure. This paper presents the results of the tests, performed on a relatively large number of compacted test specimens, where the conventional index parameters, used to identify compacted soils, were supplemented with a suction–water-content curve and measurements of “mould” suction. Correlations were established between the optimum water content and the suction–water-content curve for representative samples, and the influence of the mould suction on the vertical deformation of the compacted samples during inundation in oedometers was studied.20112018-06-13 10:01:17Znanstveno delo70768ISSN: 1854-0171UDK: 624.12/.14OceCobissID: 215987712COBISS_ID: 5668193ISSN pri članku: 1854-0171NUK URN: URN:SI:UM:DK:IZKFSNXKslFakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru
