Abstract:In soil mechanics the Atterberg limits are the most distinctive and the easiest property of fine-grained soils to measure. As they depend on the same physical factors as the other mechanical properties of soils, the values of the liquid and plastic limits would be a very convenient basis for their prediction. There are many studies concerning the use of the Atterberg limits in soil mechanics; however, their results vary considerably and are not generally applicable. This paper explains the main reasons for the different conclusions in these studies, which do not take into account the following: a) the water in fine-grained soils appears as interparticle and interaggregate pore water as well as adsorbed water onto the surfaces of clay minerals; b) the physical properties of fine-grained soils depend on the quantity of pore water only, because the adsorbed water is tightly tied on the clayʼs external and internal surfaces and thus cannot influence to them; c) the quantity of adsorbed water on the external surfaces of the clay minerals in soils depends mostly on the size and the quantity of the clay minerals, while the interlayer water quantity depends mostly on the quantity and the type of the swelling clay minerals in the soil composition and their exchangeable cations. From this it follows that for swelling and non-swelling soils, the uniform relationships between the Atterberg limits (which represent the total quantity of pore water and the adsorbed water onto the external and internal surfaces of clay minerals) and other physical properties does not exist. This paper presents some possibilities for the use of the Atterberg limits in predicting the soilʼs other properties for non-swelling and limited-swelling soils.

Title:Soodvisnosti med Atterbergovimi mejami in drugimi fizikalnimi lastnostmi vezljivih zemljin
Abstract:V mehaniki tal so Atterbergove konsistenčne meje najbolj prepoznavna in najlažje merljiva lastnost vezljivih zemljin. Ker so vrednosti teh mej odvisne od nekaterih istih dejavnikov kot vrednosti drugih fizikalnih lastnosti tal, bi lahko bili meji židkosti in plastičnosti zelo uporabni za njihovo napoved. O tem obstajajo številne študije, vendar pa se rezultati precej razlikujejo in niso splošno uporabni. V članku so pojasnjeni najpomembnejši razlogi za ta neskladja, nanašajo pa se predvsem na neupoštevanje sledečih dejstev: a) v vezljivih zemljinah se pojavlja porna voda, ki se nahaja med zrni in v agregatih glin in adsorbirana voda, ki je trdno vezana na zunanje in notranje površine glinenih mineralov; b) fizikalne lastnosti vezljivih zemljin so odvisne samo od proste porne vode, kajti adsorbirana voda, ki je trdno povezana z glinenimi zrni, nanje ne more vplivati; c) količina adsorbirane vode na zunanje površine glinenih mineralov je odvisna od velikosti in količine le teh, medtem ko je količina adsorbirane vode na notranje površine glinenih zrn odvisna predvsem od količine in vrste nabrekljivih glinenih mineralov in njihovih izmenjalnih kationov. Iz tega sledi, da za nabrekljive in ne-nabrekljive zemljine ne morejo obstajati enotna razmerja med Atterbergovimi mejami (ki predstavljajo skupno količino porne in adsorbirane vode) in drugimi fizikalnimi lastnostmi. V prispevku so predstavljene nekatere možnosti uporabe mej židkosti in plastičnosti pri napovedovanju fizikalnih lastnosti tal, nanašajo pa se na ne-nabrekljive in omejeno nabrekljive zemljine.
