Dynamic Response of Cylindrical Lining in Poroelastic Saturated Half-space Soil Induced by Internal Loading

摘要：

　　The underground structure is frequently subjected to internal dynamic loading, which will induce dynamic stress concentration of the lining.The paper studies the dynamic response of the cylindrical lining structure in half-space saturated soil under uniform transient internal loading by using Laplace transform and wave function expansion method.The surface of the half-space is treated as convex camber approximately.The wave equations in the half-space saturated soil are ex panded to infinite series.Base on continuity conditions and boundary conditions, the unknown coef ficients of wave function expansions are defined by using coordinate transform.The dynamic re sponse solutions of the cylindrical lining in saturated soil under uniform internal loading are ob tained.
