  • The Relation between Shield Machine Control and the Setting-up Quality of The Tunnel in Soft Silt Layer

抄録

The shield tunnel constructed in Ichikawa city was suffered with many cracks especially on the K-segments. To find out the reason of this, first we investigated a lot of past constraction data in similar soft silt layer. Then, we examined several countermeasures to prevent from the crack and maintain the setting-up quality. As a result, we finally found that the cracks were due to the vertical contact of the segments with the machine tail, and this phenomenon tended to happen when a machine excavated along a vertical slope.The estimated vertical force caused by this contact was around 100tf, which we should appropriately consider into the segment designing.
