TRANSIENT DYNAMIC ANALYSIS OF ELLIPSE CIRCULAR CAVITIES IN UNDERGROUND STRUCTURE

GONG Sheng-jun~1, LI Xin-xin~2 (1.Fix department of Daging second construction company,Daqing 163000,China; 2.The Construction Bureau of Daqing Honggang Section,Daqing 163511,China)  
This paper analyzed the issue of the eplipse cavity stress concentration by transient SH-wave in the FEM,founded the model of wave finite element,discussed the method's rationality,calculated the dynmic stress concentration factor at the edge of the ellipse cavity by ANSYS,gave the numerical value of the displacement at the edge of the ellipse cavity and provided the discussion.
