The paper presents a state-of-the-art review of the current understanding of the seismic
behaviour of tunnels. Emphasis is placed on recorded responses of actual tunnels during …

Current seismic codes propose designing all new buildings in isolation from their
neighbours. As a result, all modified seismic risks associated with interbuilding dynamic …

In dense urban environments, shallow underground structures widely exist in the vicinity of
aboveground structures. Under earthquakes, underground structures interact with …

More and more projects of underground structures undercrossing adjacent surface
structures have emerged in recent years. The existence of underground structure influences …

Regarding passenger safety and railway network serviceability, the effects of earthquakes
on underground transportation systems situated in seismically active regions yield a great …

During an earthquake, the presence of tunnels may affect the seismic wave propagation in
the involving soil and in turns the response of aboveground structures. At the same time, the …

The safety of subsea tunnels during earthquakes is a crucial issue for tunnel design. This
study aims to derive an analytical solution to determine the seismic response of a subsea …

An investigation on the dynamic interactions existing in a system consisting of multiple
above-ground buildings, soil and a subway station when subjected to ground motions …

Ensuring the safety of undersea shield tunnels constructed in soft marine deposits that are
subject to strong seismic motion represents a major engineering challenge. An example of …

The major principal stress direction of the tunnel is one of the most important factors affecting
the stability of an underground tunnel. This paper is devoted to the quantitative analysis of …
