摘      要：Immersed tube tunnels are usually placed on soft soil layers in cross-sea tunnelling *** to the influence of stratum conditions and slope design,the longitudinal distribution of substratum layers is generally ***,the inhomogeneous deformation of the element-joint becomes the key factor in the failure of the immersed tube ***,a corresponding calculation method for joint deformation is needed to explore the deformation law of immersed tube *** constructing a three-section immersed tube tunnel analysis model(TTM),the relationship between the two types of deformation of the immersed tube tunnel structure in a longitudinal nonuniform soft soil foundation is described,and the deformation characteristics of the immersed structure under different boundaries are *** on the mechanical behaviour of the joint and foundation,according to the Timoshenko beam on the Vlasov two-parameter foundation(VTM),considering the tidal cyclic load during the operation and maintenance period,an example analysis is ***,the deformation characteristics and development trend of the immersed tube tunnel under the influence of different soil layers are *** obtained results have a certain guiding significance for the deformation calculation of immersed tube tunnels.
