Turkey Eurasia Tunnel Project is large scale road construction project of which the total length is 14.6km. The subsea shield TBM tunnel will be constructed under Bosphorus strait and the project site is in poor condition as composite ground, high water pressure and earthquake. The design procedure of subsea tunnel was introduced with tender design materials. That procedure contains tunnel type, TBM type and the principal design items considering geological condition such as high water pressure, composite ground and seismic area. This paper states the progress for geotechnical investigation, seismic analysis and TBM tunnel design. Analysis for geotechnical investigation is in progress, aseismatic design is going on stability study for liquefaction and structure. In addition, the performance of shield TBM to be considered such as advance rate and improvement of TBM was reviewed. The plan of fire safety was also reviewed with respect to fire protection.

In this paper, we propose the new experimental using gif tunneling based on IPv4 and IPv6. HVIC developed by ETRI-SNU and vic, net by UCL in England were used during the tests. The networks used in this experiments are TEIN (TEIN:TransEurasia Information Network) that recently established between Korea and Europe and ATM-based IPv6 native network which connecting among ETRI, KOREN, SNU. We take following three scenarios into account. The one is the IPv6 tunneling based on IPv4, the other is IPv6 tunneling on IPv6 network, and the third is IPv6 native network based on ATM we propose the new experimental method using gif tunneling between IPv4 and IPv6.
