Abstract
Bakalaurā darbā ir izklāstīts pētījums par korelāciju starp grunts daļiņu izmēru sadalījumu, precīzāk, neviendabības koeficientu un maksimālo blīvumu. Izmantojot automatizētu sablīvēšanas iekārtu, pārveidotiem smilšainās grunts paraugiem tika veikti laboratorijas sablīvēšanas testi maksimālā blīvuma noteikšanai. Pētījuma gaitā tika noteikts šo paraugu faktiskais daļiņu izmēru sadalījums un citi grunts klasificēšanas raksturlielumi. Pētījuma ietvaros pielietota un pārbaudīta darba autora izstrādātā pieeja grunts paraugu granulometriskā sastāva un to dažādu raksturlielumu pārveidošanai, izmantojot dažādu frakciju izmēra minerālmateriālu. Darbā izvērtēts pielietotās metodoloģijas korektums un interpetēti iegūtie laboratorijas testu rezultāti. Pētījuma rezultāti norāda uz sakarību starp grunts neviendabības koeficientu un maksimālo blīvumu
The bachelor thesis presents a study on the correlation between the size distribution of soil particles, more specifically the uniformity coefficient and the maximum density. Using an automated compaction machine, laboratory compaction tests were performed on modified sandy soil samples to determine the maximum density. The actual particle size distribution and other soil classification characteristics of these samples were then tested. The approach developed by the author to modify the granulometric composition of the soil samples and their various characteristics using different fractional sizes of aggregate was applied and tested. The correctness of the applied methodology was evaluated and the results of laboratory tests were interpeted. The results of the study indicate a correlation between the soil uniformity coefficient and the maximum density
