Safety of tunnel structures subjected to accidental or hostile explosions inside road and
utility tunnels has attracted increasing attentions. It is essential to understand the dynamic …

The increase of transport mileage and expansion of underground space foster rapid
development in tunnel engineering, particularly in China. China has the largest number of …

Overbreak and underbreak are the crucial problems during the blasting excavation of
underground tunnels owing to their effects on the construction costs and operational safety …

The shaft is an essential structure in mining and tunnel engineering. In recent years, the
shaft lining is usually subject to deformation and damage with the increasing difficulty of …

Tunnels are classified as civil engineering infrastructure which serves various functions that
are primarily associated with transportation of vehicles and liquids. Their design and …

Natural gas poses significant risks to the safe operation of utility tunnels, which house
multiple critical infrastructure systems, including natural gas pipelines. To date, no full-scale …

In tunnel contour blasting, the rock fracturing is generally subjected to in-situ stress. In this
investigation, the rock cracking and damage in tunnel contour blasting (smooth blasting and …

In the present study, a numerical model is first calibrated against the crack networks and
pressure attenuation data in laboratory blasting test. Then, based on the calibrated …

Numerical simulation of segmental lining tunnel subjected to internal explosive loading is
carried out in this paper based on the arbitrary-Lagrangian-Eulerian (ALE) and finite …

The purpose of this investigation is to analyze the failure probability of a blast in a shallow
RC tunnel. The field blast tests are carried out, and a refined finite element model (FEM) is …
