Influence of Shield Tunnel Construction beneath a Railway on a Culvert-Embankment Transition Zone
Since the uneven settlement and the variation of the track stiffness are inherent problems of transition zones, the construction of the shield tunnel in the vicinity of the transition zone may aggravate the track geometry deterioration, maintenance demand and poor ride quality. In view of the importance of the problem, the influence of the shield tunnel construction on the subgrade uneven settlement is investigated. Results show that the reinforce treatment of the foundation is required and the recommended treatment measure is appropriate to control the uneven settlement of the subgrade in the vicinity of the transition zone.
