Considering the increasingly complex and interconnected subway tunnels linking cities, this
review argues that the overall reliability of tunnel engineering is crucial for protection when …

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 …

Social development has led to the placement of high standards on ultra-long and ultra-deep
mountain tunnels. Disasters may be encountered during the construction and maintenance …

The longitudinal bending stiffness of tunnels is one of the most important parameters for the
structural design of the tunnel longitudinal deformations during seismic loading. The aim of …

This research conducts dynamic time-history analysis and a modified cross-section racking
deformation (MCSRD) method to analyze the collapse mechanism of the Daikai Subway …

Tunnels are classified as civil engineering infrastructure which serves various functions that
are primarily associated with transportation of vehicles and liquids. Their design and …

A 1 g shaking table test is conducted to investigate seismic responses of a segmental tunnel
in sand under near-fault motions. The tunnel model is assembled with segments, bolts and …

The response mechanism of tunnels under earthquake loads is a critical issue in tunnels
located in seismically active regions. This study aims to investigate the seismic response …

In this study, the seismic behavior of a shield tunnel with an ultra-large diameter of 15 m
passing through a soft-hard stratum was investigated, using a series of 1/30 scaled shaking …

This paper aims at analyzing the influence of non-associated flow rule on face instability of a
circular tunnel in cohesive–frictional soils. A series of three-dimensional numerical …
