Various countermeasures are adopted to mitigate nearby excavation-induced deformations
and internal forces of an existing tunnel. The effectiveness and function mechanism behind …

In this study, an extensive numerical parametric study is conducted in sand to investigate the
effectiveness of countermeasures (ie, methods used to alleviate tunnel deformation) to …

The unloading process of rock mass is critical to the research of excavation disturbances of
tunnels in deep mines, and the dynamic effects induced by the release of in situ stress …

Accurate prediction of shield tunneling-induced settlement is a complex problem that
requires consideration of many influential parameters. Recent studies reveal that machine …

Predictions of excavation responses frequently differ from monitoring data due to
geotechnical uncertainties. This paper proposes an efficient Bayesian updating approach for …

The actual stress path in a rock mass during tunnel excavation is complex. To capture the
correct tunnel excavation response, it is important to correctly resemble the stress path in …

With the continuous progress of urbanization, excavation works near tunnel engineering
projects are increasing. The stress relief caused by the excavation inevitably affects the …

Tunnel uplift control is an important issue for excavation construction near an existing tunnel,
especially for long and collinear excavations. In this study, an effective anti-floating measure …

The construction of soil excavations will inevitably have an adverse effect on the adjacent
tunnels. However, the structural responses of existing shield-driven tunnels adjacent to a …

Displacement of rock mass in tunnels and underground mines is considered one of the most
hazardous phenomena that can cause the collapse of the structures. In this study, the rock …
