Tunnel boring machine (TBM) has been widely used for tunnelling in harsh environments
with deeply embedded tunnels and hard rocks. The collapse of surrounding rocks seriously …

With the rapid development of metro construction, shield machines inevitably have to
traverse a variety of complex geological conditions, leading to the frequent occurrence of …

Studying the damage evolution law of rock with directional bedding structure during the
rolling cutter rock-breaking process under high confining pressure is of great significance …

Many factors influence rock breakage during cutting processes, including cutting parameters
(attack angle, cutting depth and cutting spacing), rock properties and stress conditions. The …

Twin tunnel excavations can seriously affect the integrity of buried pipelines. In this
investigation, centrifuge model tests and numerical simulations were carried out to study the …

This paper presents a forensic numerical study on hydro-fracturing at three locations within
an excavation in a clayey till underlain by an aquifer in Ontario, Canada. The pioneering …

In this study, we address the complex geological conditions encountered during tunnel
boring machine (TBM) excavation, particularly the challenges posed by soft and hard …

A dynamic damage constitutive model is proposed based on the uni-bond dual-parameter
peridynamic (UDPD) model. The new model overcomes the shortcomings of fixed Poisson's …

The construction environment of subsea tunnels is highly complex. Revealing the
influencing factors and governing laws of surrounding rock stability as well as ensuring the …

This article investigates the fragmentation of rock during the indentation process with a
conical pick. The study explores the impact of indentation dip angle, indentation spacing …
