In the past few decades, the number of tunnels constructed next to an existing tunnel has
been gradually increasing in order to accommodate infrastructure needs in congested urban …

The increase in transportation in large cities makes it necessary to construct of twin tunnels
at shallow depths. Thus, the prediction of the influence of a new tunnel construction on an …

This paper presents a case of closely spaced twin tunnels excavated beneath other closely
spaced existing twin tunnels in Beijing, China. The existing twin tunnels were previously …

A section of closely spaced twin tunnels at Shangmeilin station on Shenzhen metro line 9
was excavated by the shield tunneling method. Part of this section lies closely beneath the …

In this study, an approach to estimate three-dimensional ground displacements induced by
shield tunneling is proposed by using the superposition method, advocating consideration of …

The main purpose of this research is to predict the ground surface settlement in tunneling of
a single circular tunnel with simultaneous changes in the mechanical properties of soil and …

Shallow tunnel construction inevitably causes local ground movements to occur. In an urban
environment, these ground movements may cause damage to existing buildings on the …

The increase in transportation in large cities has made it necessary to construct twin tunnels
at shallow depths. As far as the parallel excavation of mechanized twin tunnels is …

The construction of shallow tunnels induces a settlement trough on both the transverse and
longitudinal profile, which could cause severe damages to nearby tunnels and buildings. In …

The original stress equilibrium state of the soil is destroyed after the excavation of the double-
line shield tunnel, resulting in the settlement of the stratum above the tunnel and bringing …
