  • OBSERVATIONAL CLOSE CONSTRUCTION OF PHASE TWO TUNNEL WITH SUPPORT OF HIGH RIGIDITY AND HIGH STRENGTH FOR FRACTURE ZONE OF MUDSTONE

抄録

In Phase II tunnel construction, it is required in the first place that the safety of Phase I tunnel which is used in public should be secured. Especially, when the influence of Phase II tunnel construction is expected from the result of Phase I tunnel construction, the measure for safety reservation of Phase I tunnel is needed. In the Mt. Taro Phase II tunnel construction, the support immediately invert-closed of high rigidity and high strength was adopted in the fracture zone and the effectiveness of the support for reducing the displacement of Phase I tunnel by Phase II tunnel construction was proved. This report shows the results of measurement and the importance of an observed construction.
