Abstract:After 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.

Title:Vpliv vrojene sukcije na volumensko obnašanje zgoščenih zemljin med vlaženjem
Abstract:Vlaga zgoščenih zemljin se po vgradnji v zemeljske objekte uravnoteži z okolico. V pogojih vlažne in zmerne klime se glinene zemljine, ki so se kompaktirale na suhi strani Proctorjeve krivulje, dodatno navlažijo. Proces vlaženja spremlja zniževanje sukcije in dodatne deformacije, ki so lahko nabrekanje ali strukturni kolaps. Preiskave zemljin iz glinenih nasipov so pokazale, da se sukcija uravnoteži pri vrednostih pod ca. 300 kPa. V prispevku predstavljamo rezultate raziskav, opravljenih na zgoščenih zemljinah, v okviru katerih smo konvencionalne raziskave dopolnili z meritvami sukcije. Na izbranih vzorcih, ki smo jim določili retencijsko krivuljo, smo merili sukcijo pri različnih stopnjah zgoščenosti. Po preplavitvi smo v edometru opazovali deformacije, ki so se v odvisnosti od začetnega stanja odražale kot nabrekalni dvižki ali kolaps. S primerjavo podatkov smo ugotovili, da začetna sukcija nabitih vzorcev pomembno vpliva na značaj deformacij ob vlaženju in bi v prihodnje lahko služila kot pomemben kazalnik uporabnosti glinenih zemljin za inženirske nasipe.
