Abstract

The paper presents engineeringly reasonable transformation of surface displacements of horizontally layered half-space. The latter shows in the half-space present types of waves. It is shown that surface waves are expressed through residuums in poles of the integrand and the volume waves are expressed as integrals along corresponding branch cuts. The singularity which always appears in the basic singular solution in elastodynamics is in this case exactly excluded. In the second part of the paper the behaviour of Stonely waves is investigated in greater detail. It is shown that in the case of layers of finite thickness their appearance and velocities depends not onlyon the material characteristics of neighbouring layers but also on their thickness.

Secondary title: Inovativni pristopi k reševanju valovnih problemov v horizontalno slojevitem prostoru
Secondary abstract: V članku je predstavljena inženirsko smiselna transformacija površinskih pomikov horizontalno slojevitega polprostora, kjer so prikazani tipi valov, ki nastopajo v polprostoru. Pokazano je, da so površinski valovi izraženi kot residui izračunani v polih integranda, volumski valovi pa so izraženi kot integrali vzdolž razvejiščnih rezov. Singularnost, ki se v osnovni singularni rešitvi v elastodinamiki pojavlja vedno, je eksaktno izločena. V drugem delu prispevka je detejlno obdelan problem pojava in obnašanja Stonely-jevih valov. Pokazano je, da v primeru slojev končne debeline njihov pojav in hitrosti ne zavisijo le od materialnih karakteristik sosednjih slojev, ampak tudi od njihove debeline.
