During the rock tunnel construction, one of the critical aspects lies on the support design to
secure the construction safety. Due to the extreme complex underground geological and …

Abstract The Sichuan–Tibet railway construction has received significant attention from both
China and abroad. The new section from Ya'an to Nyingchi is about 1018.6 km long …

In the realm of drill and blast (D&B) tunneling, the design of tunnel support emerges as a
pivotal concern. As a typical knowledge-intensive task, the practical application of tunnel …

At present, shield tunneling often needs to pass through a large number of bridge pile
foundations. However, there are few studies on the influence of shield tunneling on adjacent …

Due to the extremely complex load distribution form and evolution law of soft-rock tunnels
under high geo-stress, there has been a long-term lack of theoretical support for designing …

Tunnels excavation in layered composite rock subjected to ground loads to make the best of
underground space is an important engineering problem in more and more mega-cities …

Shield tunnels will inevitably pass through viaduct piles at a close distance due to the
extensive construction of subways and viaducts in the city. In order to understand the …

High mountain valleys are characterized by the development of intricate ground stress fields
due to geological processes such as tectonic stress, river erosion, and rock weathering …

It is generally acknowledged that the stability evaluation of surrounding rock denotes
nonlinear complex system engineering. In order to accurately and quantitatively assess the …

The stress release ratio of the surrounding rock in tunnel excavation is one of the most
important indicators that affect the stress distribution and displacement of the surrounding …
