This work presents the preliminary method for assessment of the degree of the soil compaction from two types of research performed by the author. The first type of research was the tests with sensors placed directly on the rammers foot in the laboratory stand. The second stage of works was to perform test with the same stand and the machine with sensors placed on the measuring plate nearly the rammer. The results of test are processed and on the spectrum chart in the function of frequency are presented. This allow to show the differences between the loose and compacted soil. The difference type of mounting sensors has influence to vibroacoustic signal and on the frequency spectrum.

W pracy została zaprezentowana wstępna metoda oceny stopnia zagęszczenia ośrodka gruntowego na podstawie dwóch typów badań wykonanych przez autora. Pierwszym typem były badania przy użyciu maszyny zagęszczającej grunt znajdujący się w stanowisku laboratoryjnym, z czujnikami zamocowanymi bezpośrednio do stopy maszyny. Drugim etapem prac było wykonanie testów przy użyciu tego samego stanowiska i maszyny z czujnikami umieszczonymi na płycie pomiarowej obok zagęszczarki. Obróbka uzyskanych wyników i przedstawienie ich na wykresach widma w funkcji częstotliwości, pozwoliło na ukazanie różnic pomiędzy ośrodkiem luźnym i zagęszczonym. Zostały zaprezentowane różnice pomiędzy typem umieszczenia czujników na sygnał wibroakustyczny, a także na samo widmo amplitudowo-częstotliwościowe.
