Evaluation of shield tunnel segment behavior with digital photogrammetry and discontinuous manifold analysis : A case study of Fushimi Tunnel
The Shield Tunnel is adopted in many cases in order to cope with soft ground at urban areas in spite of high cost of using segments. Since the cost of segment takes from 20 to 40％ of the whole cost of construction, efforts of cost reduction are required. First, we explain some conventional design methods of a shield tunnel. Then, we propose application of the Manifold Method(MM) as the rational design method. The MM may be able to treat the rigid body action in the weak foundation appropriately by analyzing segments as blocks.We also show a plan of examination for actual deformation of tunnel segment by using precise photogrammetry method at the Fushimi Tunnel which is now under construction, which is expected to be used for verification of the MM analysis result.
