As the development of the society,underground space have been exploited by us moreand more.So the anti-seismic researches of the Underground Structures become to soimportant.In this paper, we have created structures mode of specific underground structures.After that we have done some anti-seismic researches of the structures by Elastic dynamicstheory. the scattering of out-plane line source load by a semi-cylindrical hill of cylindricalelastic inclusion with a round hole and the scattering of SH-wave by an interface cylindricalelastic inclusion with a semicircular disconnected curve which contains a round hole havebeen studied in this paper by complex variable method and the Green’s Function method.Based on the idea of domain division, the scattered waves of the semicircle sag andcircular, and the standing wave which satisfy the boundary conditions have been constructedrespectively in the study of the scattering of out-plane line source load by a semi-cylindricalhill of cylindrical elastic inclusion with a round hole. To solve the problem, equations havebeen built up with the continuity of the public boundary. After that, the dynamic stressconcentration factors which contains the factors of different size and location of the roundhole, the parameters and so on, have been counted out. After analyzing the results, we havegot some conclusion of this model.The scattering of SH-wave by an interface cylindrical elastic inclusion with asemicircular disconnected curve which contains a round hole is studied. Firstly, we can dividethe space into up-and-down parts along the interface with the idea of domain division. Toestablish a suitable Green’s Function, We have constructed the displacement functions whichmeet the boundary conditions. We can solve the problem with the integral equations whichhave been created with the stress and displacement continuity conditions of the divisionsurface. After that, the dynamic stress concentration factors considering each parameter, havebeen counted out. After analyzing the results, we have got some conclusion about thisproblem.
