A STUDY OF EARTHQUAKE RESISUTANT DESIGN METHOD FOR CROSS SECTION OF SHIELD TUNNEL
|
´˜^i‰pjF
Cross section of tunnel is in general determined by ordinary load case and rarely affected by seismic load in the tunnel with rectangular section. However a shield tunnel with circular section is influenced strongly of a unilateral load applied in earthquake motion. This study is conducted for the project of Trans-Tokyo Bay Highway. This paper shows an evaluation method of soil spring and the necessity of inertia force of the lining and shear force following of ground displacement for the seismic deformation method. Such modified method is possible to obtain almost the same level of sectional force as that of dynamic analysis using FEM model.
