Abstract: The safe operation of a subway tunnel is directly influenced by its structural serviceability.
To give an accurate evaluation on the structural performance of the operating tunnel, comprehensive inspection on the appearance of structural lining surface had been carried out.
Inspection scheme was made in achieving successful documenting defects through site investigation except organization of inspection; the scheme gives the requirements and methods to register type and extent of any defect. For the apparent defects most of the attention during inspection focused on were leakage, cracks, dislocation of joint, as well as missing of part of structural members observed on its surface. All the work is expected to give some useful references for the running tunnels of metro lines in similar conditions and provide fundamental data for further action on maintenance.
