Special Issue Information

Dear Colleagues,

In many cases, the great progress made in civil engineering technology is often the result of struggles with various natural or human-made disasters. As the scale of global engineering infrastructure continues to increase, disaster prevention and mitigation during the construction and operation periods are receiving more and more attention. In recent years, strong earthquakes have occurred frequently all over the world, leading to a large number of buildings, bridges, and tunnels being destroyed; moreover, the damage to infrastructure owing to secondary disasters caused by earthquakes, such as geological disasters, fires, and tsunamis, cannot be ignored. In addition, more frequent historic extreme climates seriously challenge the sustainability of existing structures and are therefore seen as a new type of engineering disaster. At the same time, due to the increasing tension in the global political situation, current and potential wars have posed a great threat to various engineering structures. Therefore, the ability of civil infrastructures to defend against military strikes, which can be treated as artificial disasters, has also become the focus of engineers. Therefore, it is very necessary to upgrade and improve the theory and technology of engineering disaster prevention and mitigation.

In this Special Issue, we are looking for papers related to innovative achievements from the different perspectives of engineering disaster prevention and mitigation. The guest editors cordially welcome high-quality papers focusing on, but not limited to, the following topics:

  • Theoretical and technical progress in disaster prevention and mitigation forecasting;
  • Engineering disaster investigation and statistical analysis;
  • Disaster chain simulation and inversion;
  • Disaster resistance performance and design method of infrastructure (i.e., earthquakes, fires, geological hazards, blasts);
  • Theory and technology of geological disaster protection;
  • Novel protective structures;
  • Sustainability of engineering structures under extreme climates;
  • Engineering disaster monitoring, early warning, and control technology;
  • Emergency rescue and engineering reinforcement;
  • The application of intelligent technology in disaster prevention and mitigation.

We look forward to receiving your contributions.

The derailment of a high-speed train in a tunnel will cause a very serious accident, but there are few research articles on anti-collision facilities in tunnels. In order to promote the sustainable development of high-speed trains and reduce the severity of accidents caused by derailment in tunnels of high-speed trains, this paper puts forward a crash barrier scheme in tunnels through the method of numerical simulation; the coupling finite element model of train–crash barrier–tunnel is established by using ABAQUS. The changes in lateral velocity and lateral displacement after the train hits the crash barrier without embedding steel bars are explored. We also explore the influence of different reinforcement amounts on the changes in the lateral speed and lateral displacement of trains under the condition of embedding steel bars. The results show that with the increase in stirrups and vertical reinforcement, the anti-impact and sustainable operation capability of the crash barrier are greater. It can also be seen from the lateral displacement of the train that the train shows the reverse movement trend, and the crash barrier plays a good role in intercepting the train. These research results can provide a reference for the sustainable development of transportation infrastructure construction. Full article

With an increase in the service time of high-speed railway tunnels, various defects caused by construction-quality defects in the secondary lining begin to appear. How to evaluate the safety of such tunnels and take countermeasures is very important for the safe operation of tunnels. Based on the load-structure method and a numerical simulation, this paper studied the short-term and long-term safety of the missing section of anti-crack reinforcement mesh in the plain concrete lining of a high-speed railway mountain tunnel. The short-term safety evaluation considered the influence of negative pressure caused by aerodynamic effects. The long-term safety evaluation considered the combined influence of the surrounding rock and concrete deterioration and the negative pressure and concrete fatigue damage caused by aerodynamic effects. The results showed that under the negative pressure generated by aerodynamic effects, the minimum tensile safety factor of the lining in the defective section increased by 3.8%, while the minimum compressive safety factor of the lining decreased by 7.9%. The negative pressure generated by the aerodynamic effects had little impact on the short-term safety of the lining in the defective section. During the long-term safety evaluation, the overall safety of the defective section decreased significantly, and the minimum tensile and minimum compressive safety factors of the lining decreased by 59.4% and 66.8%, respectively. The calculation results for the initial design do not meet the long-term design requirements and cannot guarantee the long-term safe operation of the tunnel. Finally, two new strengthening methods of galvanized steel mesh-short bolts and galvanized corrugated steel plate-short bolts were proposed to strengthen the defective section of the concrete lining, so as to improve the ultimate bearing capacity and toughness of the plain concrete lining structure.
