“…Dažniausiai gruntai ir jų inžinerinės geologinės sąlygos (Dundulis ir kt., 2008) yra tiriamos statinėmis apkrovomis. Atliekant inžinerinius geologinius tyrimus plačiai naudojami statiniai kūginės penetracijos bandymai (Žaržojus, Dundulis, 2010). Kartais, jei yra neįmanoma ištirti grunto kūginės penetracijos, taikomas dinaminis zondavimas (Žaržojus ir kt., 2013; Žaržojus, Kelevišius, 2016).…”

Straipsnyje yra apžvelgtos grunto liekamosios deformacijos ir įvertintas liekamasis grunto deformacijų modulis esant skirtingam grunto apkrovimų ciklų kiekiui. Šie tyrimai leidžia prognozuoti inžinerinio geologinio pagrindo, kuris perima apkrovas, elgseną esant skirtingam apkrovimo ciklų kiekiui (intensyvumui). Bandymai atlikti su triašio slėgio aparatu, imituojant automobilių kelių sukeliamas ir perduodamas apkrovas pagrindams. Gruntas ištirtas esant skirtingiems apkrovų intensyvumams ir grunto gyliams. Gauti rezultatai parodė, kad liekamasis grunto deformacijų modulis labai priklauso nuo grunto bandinio apkrovimo ciklų kiekio ir apkrovų intensyvumo. Nustatyta, kad bendrosios tirto grunto deformacijos nebuvo didesnės nei 2,0 %. Matuojant bandinio vertikalias deformacijas ties bandinio viduriu, liekamosios deformacijos nebuvo didesnės nei 0,5 %. Gauti rezultatai yra labai vertingi prognozuojant / modeliuojant inžinerinio geologinio pagrindo elgseną esant skirtingam apkrovų ciklų kiekiui ir intensyvumui. Rezultatus galima lengvai pritaikyti tokio paties grunto sluoksnio skirtingiems gyliams (įvertinti liekamąjį grunto sustiprėjimą).

“…In engineering geological and geotechnical research in Lithuania, the soil Young's modulus E for more than 30 years is calculated from the results of CPTs (Žaržojus & Dundulis, 2010). The calculations are based on empirical Equations ( 1)-( 4) proposed by Brilingas (1988) and still are used in their original form.…”

Simplified methods based on cone penetration test results are commonly used to determine soil deformation modulus, depending on the engineering geological and geotechnical conditions and the complexity of the computational approach. This paper reviews some empirical equations based on the results of the cone penetration test and gives recommendations for the assessment of Young’s modulus, oedometric modulus and residual modulus from the cone penetration test result, according to the Lithuanian technical requirements and other standards. Theoretical interpretations of results are presented together with practical examples for coarse and fine soils, limits of empirical equations application are explained.

“…due to the extreme non-uniformity of anthropogenic grounds made with hard coal mining waste and a need for deep geotechnical investigation, the only proper method of the field investigation of grounds is dynamic probing using super-heavy (dPSH) standard equipment [16]. however, the main method of soil investigation used around the world is the cone penetration test (cPt), for which a large theoretic base has been developed for years [17].…”

Assessment of the DetermineD GrounD CompACtion of AnthropoGeniC soilContAininG hArD CoAl mine WAste usinG the Dpsh DynAmiC probe the shortage of investment areas may be at least partially satisfied by the development of reclaimed post-mining areas. these are often subsidence zones levelled with hard coal mine waste or reclaimed sub-level old dumps of this waste. From the geotechnical point of view, such grounds represent anthropogenic grounds containing mine waste, and they are considered as possessing unfavourable properties in terms of the foundation of building structures. the paper initially presents the analysis of the properties of waste from the hard coal mining industry, emphasising that they expose several beneficial properties enabling their safe use. the second part of the article is devoted to the determination of soil density using the dPSH probe. It has been found that the applicable standards lack complex relationships that would allow for a reliable interpretation of the measurement results in a wide range of soil types. the last part presents exemplary results of measurements made with the dPSH probe at a construction site. The obtained results allowed for the formulation of several conclusions regarding the possibility of building on a ground made of hard coal waste and the use of dynamic sounding to assess the geotechnical properties of such anthropogenic soil.Keywords: anthropogenic soils/ground; dynamic probing; hard coal mine waste; made grounds; postmining land reclamation notation a 1 -coefficient dependent on the type of soil and the presence of groundwater a 2 -coefficient dependent on the type of the probe C u -coefficient of grain size uniformity e max -the maximum porosity index (at the loosest grain arrangement) e min -the minimum porosity index (at the densest grain arrangement)
