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 …

A reasonable spacing between tunnels is very important in deeply buried tunnels, as it may
mitigate the risk of rockburst occurrence. This spacing is particularly important for tunnels …

In the present work, important aspects of time-dependent nonlinear 3D finite element (FE)
models for deep tunnel advance by the New Austrian Tunneling Method (NATM) …

Cracking and crushing were observed in the first tunnel lining of the Kaidagu double-arch
tunnel (China), excavated in weathered surrounding rock. This concrete damage occurred …

The use of an underground transportation network to solve urban traffic problems is a
practical solution. Shiraz, one of the most famous touristic cities of Iran, is developing its own …

The tunnels between the Chenglinlu station and Jintanglu stations of Tianjin Metro line 5 are
by far the longest overlapping tunnels in China. The tunnels were constructed with earth …

This paper presents an assessment of the influence of the lagging distance between two
horizontal tunnel faces of the side-by-side twin tunnels on the responses of the adjacent …

The mechanical analysis of multiple tunnels at great depth is an extremely common problem
in practical engineering. Previous studies usually used the Schwarz alternating method to …

Twin curved tunnels are often encountered in shield tunnelling, where significant
complexities in densely exploited underground space are observed. In this study, the ground …

The excavation of a tunnel using a shield machine induces an impact on the tunnel lining
responses and settlements. Three-dimensional finite difference calculations of twin …
