| Abstract |
This paper presents analytical solutions to the dynamic response of a lined tunnel in the covering soil layer of composite strata under the incident SH waves by using the complex function method and conformal mapping technique. It is more important to analyze the scattering of elastic waves in the composite stratum because of the existence of boundaries between the soil layers. By applying the conformal mapping technique instead of the large-arc assumption method, the straight boundaries of the covering layer and the circular boundaries of a lined tunnel are transformed into several circles on other complex planes. An infinite linear equation system is established and is solved based on the stress and displacement boundary conditions at the boundaries of the composite stratum and the tunnel lining. The impacts on the dynamic response of a lined tunnel in several types of composite strata, "soft-over-hard" and "hard-over-soft" with "flexible lining" and "rigid lining" are analyzed through the calculation examples. |
