Abstract：

In　order　to　explore　the　characteristics　of　the　seismic　response　of　shallow-depth　underground　structures　affected　by　basin　surface　waves,　a　comparative　analysis　regarding　the　dynamic　response　of　subway　stations　under　the　effects　of　a　basin　surface　wave　versus　a　single　seismic　wave　was　performed　with　FLAC　finite-difference　software　using　a　double-layer　two-span　box　framework　of　a　subway　station　as　an　example.　The　results　show　that:　the　dynamic　response　of　underground　structures　is　amplified　under　the　basin　surface　wave　effect　and　the　amplifying　factors　of　relevant　parts　are　reduced　to　some　extent　with　an　increased　structure　depth;　the　weak　points　of　underground　structures　are　not　changed　under　the　basin　surface　effect　in　light　of　aseismicity;　and　it　plays　a　key　role　in　the　ground　motion　characteristics　of　a　seismic　wave　on　underground　structures.
