| Research Abstract |
Numbers of tunnel constructions under unfavorable ground condition have increased recently. Current tunnel structure itself cannot conform to large deformation when the large force from ground occurs and acts on the structure. The mechanical characteristics of the tunnel with the mechanism to assume to absorb the large force and/or displacement correspond to the deformation were examined in this study through model test and numerical analysis. Consequently, the existence of the mechanism influences on the relation between force and deformation, the position and occurrence load of cracks in structure and the strain over the structure is alleviated.
