- STUDY ON APPLICABILITY OF SEISMIC DEFORMATION METHOD IN SEISMIC DESIGN OF MULTI LAYER CUT-AND-COVER TUNNEL AND INFLUENCE OF SPRING COEFFICIENTS
説明
The applicability of Seismic Deformation Method (S. D. M) for multi layer cut-and-cover tunnel has been examined by comparing the results among FEM S. D. M, frame S. D. M and 2-D dynamic analysis (FLUSH). Because setting of spring coefficients is important as for the frame S. D. M, the influence of spring coefficients has been examined. As a result it is indentified that if the spring coefficients can be evaluated adequately, the frame S. D. M is able to be applied to seismic design even though the height of structure changed. And, from the sensitive analysis of spring coefficients it is understood that the effects on the results due to the horizontal springs (shear spring of top/bottom slab, normal direction spring of side wall) are great, but when the height of structure increased the effects by all spring coefficients become small. In the other way, the results with good precision can been obtained by using FEM S. D. M even if the height of structure changed.
