Abstract

There is an increasing demand for safe tunnel construction using the shield tunneling method in urban areas because of construction conditions and other constraints. However, the shield machine cost is so high that the shield tunneling method is not usually used for building short tunnels.
In this report, we describe some shield machine cost reduction schemes. In these schemes, main parts of machine for the construction of short-distance double-track subway tunnel can be used for the construction of neighboring single-track tunnels after the double-track tunnel has been constructed.
