1. Reševanje problemov mehanike talPrimož Jelušič, 2021, higher education textbook Abstract: Namen učbenika je aplicirati zakonitosti mehanike tal na praktičnih primerih. Prikazani so osnovni postopki za ovrednotenje fizikalnih in mehanskih lastnosti zemljin, ki so osnova za učinkovito reševanje problemov v geotehniki. Glede na obstoječo literaturo s področja mehanike tal je vsebina učbenika razdeljena na 16 poglavij: Uvod, Klasifikacija zemljin, Tri-fazni sestav zemljine, Napetosti v zemljini, Napetosti v sloju tal, Darcyjev zakon, Prepustnost zemljin, Precejanje podzemne vode, Napetosti in deformacije, Eno-dimenzionalni tlak, Konsolidacija, Lezenje, Strižna trdnost, Določitev parametrov strižne trdnosti, Napetosti-teorija elastičnosti in Stabilnostna analiza.
Keywords: mehanika tal, lastnosti zemljin, napetosti v sloju tal, konsolidacija, strižna trdnost, stabilnostna analiza

2. Izbrana poglavja iz mehanike talPrimož Jelušič, 2021, reviewed university, higher education or higher vocational education textbook Abstract: Namen učbenika je predstaviti osnovne postopke za ovrednotenje fizikalnih in mehanskih lastnosti zemljin, ki so osnova za učinkovito reševanje problemov v geotehniki. V učbeniku so podane zakonitosti, ki opisujejo fizikalne in mehanske lastnosti zemljin. Vsebine mehanike tal so medsebojno povezane, zato jih je težko ločiti na posamezna poglavja. Glede na obstoječo literaturo s področja mehanike tal je vsebina učbenika razdeljena na 16 poglavij: Uvod, Klasifikacija zemljin, Tri-fazni sestav zemljine, Napetosti v zemljini, Napetosti v sloju tal, Darcy-jev zakon, Prepustnost zemljin, Precejanje podzemne vode, Napetosti in deformacije, Eno-dimenzionalni tlak, Konsolidacija, Lezenje, Strižna trdnost, Določitev parametrov strižne trdnosti, Napetosti-teorija elastičnosti in Stabilnostna analiza.

3. Vloga mineralogije v mehaniki zemljinBojana Dolinar, 2002, original scientific article Abstract: The research of consistency of limits according to Atterberg is of key importance in soil mechanics because it determines, in a simple way, the results of interactions between solid and liquid phases in soils, and thus provides possibility to classify them in groups with similar mechanical properties. In most cases, the results of these investigations provide a good basis for predicting other properties, such as deformability, expansion, hydraulic conductivity and strength of soils. This proves that the basis factors influencing the values of consistency limits and other mechanical properties are the same. It is known that the values of consistency limits depend on the type and quantity of clay minerals in soils. The article focuses on experimental evidence of dependence between the quantity of water at the liquid limit for soils and type, portion and specific surface of clay grains. Experiments were performed with nonmineral materilas, their mixtures and samples composed of clay- and non-clay components. It was established that in parallel orientation of clay particles the quantity of water between graind and liquid limit is dependent on their external specific surface.
