Natural soils exhibit spatially non-uniform properties, bringing some uncertainties on the
evaluation of tunnel stability. This study therefore investigates the face instability and in …

To investigate the longitudinal deformation profile (LDP) of a deep tunnel in non-hydrostatic
condition, an analytical model is proposed in our study. In this model, the problem is …

Granular materials used in engineering structures tend to experience arching under different
geotechnical factors. Arching is a factor of load transfer from the destroyed zone to stable …

Earth pressure balance (EPB) shield tunnelling plays a crucial role in urban infrastructure
development but faces challenges due to potential face instability. Previous studies often …

Shield tunneling inevitably passes through a large number of pile foundations in urban
areas. Thus, an accurate assessment of tunneling-induced pile displacement and potential …

This paper investigates the role of basement depth on the response of framed buildings to
tunnel construction in sandy soil using finite element modelling. Six frames are considered …

The soil mass above the tunnel generally yields due to the tunnel volume loss. Depending
on the amount of the volume loss, soil unit weight, overburden height and internal friction …

Urban tunnelling projects pose significant risks to the integrity of nearby structures due to
ground movements induced by the excavation process. Embedded walls are commonly …

To reduce tunnelling induced damage of buildings, a 'protective wall'is sometimes
constructed between the location of the new tunnel and existing foundations. One of the key …

Compaction grouting has been successfully applied in shield tunneling works to mitigate the
surface settlements. At present, grouting injection is usually undertaken with cautious …
