Outline of Final Research Achievements

Shield tunnelling method is a standard method to construct a urban tunnel. In the case of shield tunnelling, the proper control of shield behavior is essential to ensure a planned tunnel alignment, since tunnel linings are installed inside of the TBM.
This study aims to develop a theoretical shield control method in three dimensional space and carried out the followings: 1) the development of shield control method for combined curved alignments; 2) the development of shield control method taking account of force equilibrium conditions; and 3) the examination of the newly developed method by site-data and numerical experiments.
The results of this research enable shield control with more realistic in a combined curved alignment in three dimensional space, of which the use is expected to increase near future. This could contribute to improve the accuracy of tunnel construction, to reduce the damage of segments during construction, and finally to improve the durability of tunnel.
