An Analytical Solution to Seismic Response of Segment Tunnel Lining Considering Local Stress and Deformation of Segment Joints
摘要
Abstract
A closed-form solution of seismic design of shield tunnel considering effect of local stress and deformation of segment joint is proposed.The deformation and rotation of shield tunnel's segment lining with joints is analyzed,assuming the 45 degree direction has the maximum deformation.Then the contact stress distribution of the interface at the joints are also formulated.Compared with models proposed by Sedarat in which joint is not incorporated,the bending moment distribution of the whole segment lining is found significantly changed,and localized concrete crush occurs at the joint interface.So,the segment joint should not be neglected during seismic design of segment tunnel.关键词
