The　series　solution　of　an　underground　cylindrical　lined　cavity　subjected　to　incident　plane　SH　waves　was　used　to　quantitatively　analyze　the　effect　of　incident　wavelength,　incident　angle,　diameter　of　the　cavity,　and　liner　stiffness　on　dynamic　stress　concentration　factor.　The　numerical　results　show　that:　(1)　the　rigidity　of　liner　has　great　effect　on　dynamic　stress　concentration　factor,　the　factor　is　highest　for　a　cavity　with　rigid　lining,　and　it　takes　second　place　for　an　unlined　cavity,　and　it　is　lowest　for　a　cavity　with　flexible　lining;　the　dynamic　hoop　and　axial　stress　concentration　factor　can　be　83.49　and　85.31;　(2)　the　frequency　and　the　angles　of　the　incident　waves　also　plays　an　important　role　in　the　dynamic　stress　concentration　factor.
