Brittle failure, also known as rockburst, is a violent phenomenon that occurs during the
excavation of hard rock in areas with high geostress, particularly at great depths. The …

Automation of construction machines has grown rapidly in recent years as a response to the
need to increase productivity, increase construction safety, decrease costs, and overcome …

The number and complexity of tunnel systems will surely increase with ever increasing
population and urbanization. Although most tunnel construction projects have been …

This paper presents a methodology to systematically assess and manage the risks
associated with tunnel construction. The methodology consists of combining a geologic …

Rockburst is characterized by a violent explosion of a block causing a sudden rupture in the
rock and is quite common in deep tunnels. It is critical to understand the phenomenon of …

Rockbursts frequently occur in deep underground excavations in a sudden or violent
ejection of blocks of rocks from excavation walls. In addition to understanding rockburst …

A recent rotational face collapse mechanism is extended to compute critical pressures, in the
context of the upper-bound limit analysis, for tunnels in layered (or stratified) ground. The …

Deep underground excavations in mining and civil engineering are subjected to high in-situ
stresses which can cause rockburst. Rockburst is an instantaneous release of a large …

This paper proposes a novel hybrid approach that merges fuzzy matter element (FME),
Monte Carlo (MC) simulation technique, and Dempster–Shafer (D–S) evidence theory to …

Abstract The three-dimensional (3D) deformation of underground tunnel is meaningful for
assessing its mechanical stability, especially for the tunnel with large deformation disaster …
