With the increase in the number of underground structures, it is common to encounter
reinforced concrete (RC) pile foundations of existing buildings or bridges during shield …

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 …

Based on the discrete element method (DEM)-continuum mechanics coupling method, a
numerical simulation analysis is carried out to model cutting some existing bridge piles that …

This paper aims to develop a three-dimensional (3D) analytical framework to assess the
safety factors of realistic non-circular tunnel faces reinforced by longitudinal bolts under …

This paper analyzes the characteristics and mechanism of the collapse of a tunnel in
Wenzhou in fault fracture zone during rainfall based on the failure theory of surrounding …

The instability of the tunnel face is one of the biggest concerns when tunneling with an earth
pressure balanced shield (EPBS) machine. The mechanism by which the tunnel face fails is …

In some cases, the water content in granular soil increases to the extent that it becomes
saturated, which noticeably alters its responses. For example, the pore water pressure within …

This paper aims at studying the face stability of earth pressure balanced (EPB) shield
tunnels in multilayered ground with soft sand lying on hard rock considering dynamic …

In order to provide insight into the reinforcing mechanism of face bolting, in this work a series
of experimental tests and numerical simulations on reinforced and unreinforced tunnel faces …

Granular soil is commonly encountered during underground constructions in and around
urban areas. Due to the lack of cohesion in the granular soil, tunneling through it can easily …
