When high-speed trains passing through tunnels, the dramatic changing in aerodynamic pressure repeatedly acts on water-rich cracks, potentially causing further crack expansion or even more severe structural damages. This study employs the dynamic overlapping grid method and the volume of fluid (VOF) model to establish a multiphase flow coupling model of air-train-tunnel-water-rich cracks, analyzing the spatiotemporal variation characteristics, influencing factors, and mechanisms within water-rich cracks when a high-speed train passes through a tunnel. The main conclusions are as follows: (1) The pressure changes inside the water-rich cracks exhibit a significant pressure amplification phenomenon. Compared to the tunnel wall, the increase in positive peak value (<em>C_p</em>_,max) and negative peak value (<em>C_p</em>_,min) of the aerodynamic pressure near the crack tip is as high as 22.91 % and 51.71 %. (2) The pressure variation trend along the length direction inside the water-rich crack has a distinct one-dimensional feature, while along the depth direction is significantly different. The pressure waves do not change with depth of the crack in water-free section, but the pressure fluctuation amplitude in the water-rich section increases with the depth. (3) The positive and negative pressure waves exert thrust and suction forces on the water body inside the water-rich crack, leading to fluctuation in air density near the crack tip, thus causing oscillation and amplification in the pressure. The water in the water-rich cracks exhibits increased motion amplitude and peak acceleration with greater depth, causing the pressure in water also intensifies. (4) Compared to those outside the crack at 300 km/h, the <em>C_p,</em>_max near the water-rich crack tip increased by 6.69 %, 77.98 %, and 62.03 % when the train speed is 300 km/h, 350 km/h, and 400 km/h, and the <em>C_p,</em>_min increased by 57.71 %, 111.25 %, and 161.73 %, respectively. The maximum pressure fluctuation amplitude occurring at a water content of 80 %. The results can provide theoretical basis for the healthy and high-quality operation of high-speed railway tunnels.</div></div>","PeriodicalId":49414,"journal":{"name":"Tunnelling and Underground Space Technology","volume":"161 ","pages":"Article 106529"},"PeriodicalIF":6.7,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a heating power energy tunnel with the similarity ratio of 1:5 is constructed using the shield-driven method in Beijing, and experiments are performed under different initial air temperatures in the tunnel, fluid temperatures at the inlet and fluid velocities in an intermittent operation mode. The results show that the heat flux extracted (<em>q</em>) ascends with increasing the tunnel initial air temperature. when the initial air temperature changed from 40 to 60 °C, the heat flux <em>q</em> increases by 33.3 % after 120 min operation. The thermal stress of the segment lining (<em>σ</em>_t) exhibits logarithmic growth with the increment of tunnel initial air temperature. Both <em>q</em> and <em>σ</em>_t show a negatively linear relationship with the inlet fluid temperature of the absorber pipe. <em>q</em> and <em>σ</em>_t also increase logarithmically with fluid velocity in the absorber pipe. Sensitivity analysis indicates that, among the three operation parameters, the variation of tunnel initial air temperature has the highest impact on <em>q</em> and <em>σ</em>_t.

There are three spatial relationships between the shield shell and the segments: completely at the shield shell, detaching from the shield tail, and completely detached from the shield tail. The squeezing action of the shield shell deflection often leads to the floating and dislocation of the segments and even damage cracking. Based on a refined 3D numerical calculation model considering the multi-source load coupling action and the multi-sensors field tests, this study reveals the mechanical and deformation characteristics as well as the damage evolution mechanism of segments under the deflection squeezing of the shield shell. The research results indicate that the adjacent dislocation of the segments mainly occurs during the segment detaching from the shield tail, and the internal dislocation in the first segment after the shield tail is the largest. The increase in the deflection angle of the shield shell will lead to a more significant increase in the overall vertical compression deformation of the segment. Resulting in the maximum increase in internal dislocation and bolt stress on the upper side of the first segment behind the shield tail. In addition, the adjacent and inter dislocation caused by shield shell deflection is the main cause of segment damage and cracking. The segment damage is mainly tensile damage at the positions of the two sides and upper circumferential joints. The increase in the deflection angle has the greatest impact on the overall tensile damage of the segment that is detaching from the shield tail. Controlling the vertical displacement of the rear end of the shield shell within 50 mm can reduce the floating displacement of the segment by about 67 %.

In this paper, a traffic-based resilience assessment model was proposed, considering both the accident duration and distribution of traffic demand. In this model, the influence of factors, such as tidal traffic flow and traffic capacity could be intuitively reflected. Besides, the disruption and recovery process of traffic performance could be accurately predicted. Firstly, the methodology for developing the proposed resilience assessment model was discussed in details. Subsequently, a case study focusing on a cross-river tunnel in Shanghai was conducted to exhibit the application. Then, the evolution of performance curves and resilience assessment under different conditions, such as time of fire accident, fire intensity and distribution of traffic demand were investigated. Finally, effectiveness of two measures on improving traffic resilience, including enhancing overall efficiency of emergency services and conducting traffic managements in time was discussed. The results indicate that resilience decreases when fire accidents occur during holidays, or at times when traffic demand is high.
