| description | The paper includes experimental research using the Split Hopkinson Pressure Bar to determine dynamic compression curves and strength dynamic parameters to depend on the strain rate and moisture for silty sand soil samples. Those experiments are oedometric type based in a rigid confining cylinder. Samples of silty sand with fine a fraction content were taken for the study. To ensure sufficiently uniaxial strain of the tested material, the soil samples were placed in properly prepared casings made of duralumin for the needs of the tests. Thanks to the use of measuring strain gauges on the initiating and transmitting bars, as well as the casing, the nature of the loading pulse was obtained, which was then subjected to the process of filtration and data processing to obtain the nature of the incident, reflected and transmitted wave. During the above dynamic experiments with the representative of silty sand soils, it was observed that its dynamic compaction at a high strain rate is different than in the case of the Proctor test. This is due to higher compaction energy, which additionally changes the grain size by destroying the grains in the structure. The paper presents the results of particle size distribution analysis for two different types of soil samples - this type of analysis is unique. Hence experiments should be further continued for such soils with different granulations and various moisture using, for example, Hopkinson measuring bar technique to confirm for other silty sand soils that are often subgrade of various engineering objects. |
