The study of the elastic properties of carbonate rocks on a base of laboratory and field measurement

Abstract

The main aim of the paper was to determine the anisotropy coefficient on the basis of the laboratory measurement and also to calculate the dynamic elastic moduli using laboratory measurements and compared them with field measurements. Samples of carbonate rocks like dolomite and limestone for investigation were carried out from different quarries from the south part of Poland. The shape of samples is a cuboid with dimensions 0,1 x 0,05 x 0,05 m. The Pundit Lab+ equipment was used for tests. It measures the transmission time of an ultrasonic wave. P- and S- wave velocity are obtained for each sample. Seismic velocity values allowed for the calculation of the dynamic elastic moduli. The application of laboratory methods allowed obtaining information about the physical properties of rocks. This knowledge makes easier recognition in preliminary stages during engineering study
