Pateikiami specifiniai reikalavimai grunto šlaitų tankinimo mašinoms. Siūloma ilgus šlaitus tankinti prikabinamais vibrovolais, pateikiama eksperimentinio turinio metodika ir rezultatai. Grafiškai pateikiamas įtempimų kitimas grunte pagal gylį priklausomai nuo šlaito statumo. The article deals with the peculiarities of soil compaction on slopes which determine special requirements for compacting machines. The paper suggests to use trailer vibrorollers for compaction long slopes. The technique and results of the first experiments which have been carried out to determine the optimal parameters of vibrorollers intented to compact the soil slopes as well as compaction depth dependences (stress distribution in soil) on the steepness of slopes are submitted in the paper. The recomendations concerning the vibroroller type of operations are presented in the paper as well.
