For verifying the loading ability and stability of lining segment,it s necessary to do the lining whole wreath experiment.

The test results can guide parameter design of similar lining segment.

The distribution law of structural internal force of lining segment is analyzed,and influences of different calculation method on structural design of shield tunnel lining are also discussed.

Model Test and Numerical Simulation of Segment Lining for Nanjing Changjiang Tunnel;

The main topics under discussion here were: corrosion mechanism of RC segment lining structures,main factors affecting the durability of RC tunnel structures,durability of bolts connected segment joints and water-proofing materials,durabil.

The mechanical properties of segment linings for deep and long tunnels of west route of South-to-North Water Transfer Project are analyzed by using numerical simulation method.

In order to probe into the 3D mechanical behaviors of shield tunnel segmental linings,a shell-spring-contact model for load and structure interaction was set up by using thick shell,spring,solid and contact elements to analyze forces acting on shield tunnel segments.

Finite elements analysis of TBM tunnel segments;

By comparison and analysis, the s u itable thickness for lining segment and mechanic behavior for different installa tion is gained.
