“…As the mechanical analysis method for tunnel structure is recommended by the International Tunnelling Association, the load-structure method (bedded-beam model) is widely used in the safety evaluation of tunnel structures [21,[33][34][35][36]. Based on the plane strain condition, the load-structure method uses springs to simulate the interaction between the lining and surrounding rock.…”

“…Due to the comprehensive influence of design concepts, construction conditions, geographical environment and other factors, defects in lining structures occur from time to time in the early stages of construction, which means tunnel operation may suffer potential safety hazards [20]. Ye et al [21] found that problems such as cavities and uneven lining thickness caused by blasting were ignored during the construction of Liupanshan Tunnel, resulting in cracks, water leakage and bottom damage to the lining structure During the long-term operation of a tunnel, due to the joint effect of internal and external factors, the surrounding rock and concrete will deteriorate, which will reduce the safety of the lining structure [10]. Sandrone et al [17] proposed a long-term safety analysis method for tunnels based on the converging-constraint method for the deterioration of surrounding rock and concrete under aging, weathering and other conditions.…”

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.

“…However, TOR ignore the impact of unsafe behavior and safety culture on construction safety (Fang et al, 2020). EOR attempt to ensure the safety of construction site and the public through the management and control of complex geological and technical risks during the mega infrastructure construction process (Wang et al, 2019;Chen et al, 2020;Ye et al, 2020). Although EOR has greatly improved safety performance, the risks of the mega infrastructure construction often have different characteristics, which makes the conclusions obtained by EOR difficult to apply to other projects.…”

“…Accident statistical methods provide guidance for accident prevention by classifying and counting accidents in different categories (Lopez Arquillos et al, 2012;Wang et al, 2020b), but the categories are often simple indicators such as time and gender rather than complex indicators such as safety awareness. The purpose of safety evaluation and the SMS establishment is to make up for the shortcomings of project safety management (Zhou et al, 2015;Ye et al, 2020), but most of these studies focus on a project rather than a large amount of accident data. Therefore, this study attempts to analyze HCA data from a different perspective.…”

PurposeThe purpose of this study is to establish a modified accident causation model for highway construction accidents (ACM-HC) and describe the establishment process of the ACM-HC.Design/methodology/approachBased on the 2–4 Model, a framework of the ACM-HC was constructed, and the accident causal factors (CF) were extracted from four aspects of human, material, environment and management. In addition, association rule mining (ARM) was introduced to analyze accident investigation reports to obtain the interrelationships between the factors. Based on the framework, factors and ARM results, the ACM-HC was established. Finally, the ACM-HC was verified with a tunnel collapse accident.FindingsBoth the external and internal causes of contractor cause accidents. The flaws of safety management of other stakeholders are external causes. In terms of the internal causes, there are four stages: direct causes, indirect causes, radical causes and root causes. More specifically, the direct causes refer to the unsafe acts and the unsafe conditions; ineffective safety supervision and poor individual factors of frontline workers constitute the indirect causes; the radical causes lie in the flaws of construction procedures and technical schemes; the root causes are related to the poor individual factors of decision makers and managers.Originality/valueThe ACM-HC expresses the causes, sequence and mechanism of highway construction accidents in a visual way. In addition, this study describes a process of using a qualitative–quantitative hybrid approach to establish a modified ACM, which provides a different perspective for the establishment of an ACM.
