“…In fact, the OSRP and the FHF are coupled acting on the lining support, we can't easily distinguish them. Even though, many researches about field measurement have been done to understand the change law of the tunnel temperature (Kozlowski, 2009;Tan et al, 2014;Zhou et al, 2016;Jun et al, 2017;Li et al, 2017;Xing et al, 2017;Zeng et al, 2017;Zhang G et al, 2017;Zhao et al, 2019;Wu et al, 2020). Jun et al (2017) measured the temperature of the air inside the tunnel, the road pavement, and the lining surfaces of a total of 104 surveyed tunnels, then he analyzed the statistical law of data.…”

The frost heave force (FHF) is one of the most important reason of inducing freezing damages of tunnel in seasonal frozen regions. Analyzing the change law of FHF is helpful to design for avoiding freezing damages in the tunnel lining. Field measurement is an approved method used in mechanical analysis of tunnel lining, however, it is difficult to measure the FHF directly, which is changed coupled with the original surrounding rock pressure (OSRP). In this paper, in order to clarifying the change law of the FHF, a new measuring method was presented. The best advantage of this method is that the FHF could be separated from the OSRP by measuring the surrounding rock temperature and the lining pressure at the same time. A lot of field measurement work about the FHF was conducted based on Jichoushan tunnel and the change law of the FHF was analyzed using the presented method. The results can provide preference for the antifreeze design of tunnel in seasonal cold regions.

“…The existing researches (Tan et al, 2019; Yang et al, 2018) indicated that water pressure, soil pressure and temperature are the main loads to influence the stability of structure. In traditional studies, temperature is considered as evenly distributing in tunnel, which is not agree with the actual conditions (Jun et al, 2017; Oluwaseun et al, 2019). According to the results provided by field investigations, the natural characteristics of temperature distribution of concrete structures during the period of server life should be considered as heterogeneous and uneven (Yang et al, 2018).…”

Temperature variation is an essential factor to influence the stability of concrete structure. In contrast to the uniform distribution of temperature in most existing approaches, this paper aims to study the natural temperature distribution in concrete structure and analyze its impact on structural mechanical behaviors in field. As a case study, an underwater shield tunnel is investigated using the presented method. Firstly, temperature sensors are installed in different positions to achieve real-time monitoring in field. Then, a statistical model is derived by monitoring data to describe temperature variation. As a core component of the approach, the devised statistical model is integrated into our program to determine the external loads imposed on model. Finally, the mechanical behaviors of concrete structure are discussed under uneven temperature distribution. Analytical results indicated the magnitudes of temperature distribution is related to different positions of structure, in which the significant distinctions can be observed at upper and lower of tunnel as well as the inside and outside structures. Also, the tensile stress of tunnel lining increases with the rise of temperature, for instance, in this case study per temperature rising would lead to an increment 25.3 KPa of tensile stress. As a promising application, the analytical results provide an assessment of concrete structure stability.

“…Half of the world's land area is covered by transient permafrost, seasonal frozen soil, or permafrost [1,2]. Cold region tunnels have been increasingly built in recent years but freezing damage to such tunnels threatens their structural and operational safety [3][4][5][6]. Aiming to solve the problem of freezing damage to cold region tunnels, investigations on their temperature field have increased.…”

Groundwater seepage significantly affects the temperature field of a cold region tunnel. Laboratory model tests are carried out to evaluate its effects, yielding four main results. First, groundwater seepage can increase tunnel air temperature and decrease the thickness and length of the tunnel insulation layer. Second, groundwater seepage and tunnel ventilation exert a coupling effect on the surrounding rock temperature. This effect is related to the surrounding rock depth. Third, the influence of the groundwater seepage velocity on the temperature of the interface between the lining and surrounding rock demonstrates a spatial difference, and the groundwater seepage leads to an uneven temperature distribution at the interface between the lining and surrounding rock. Furthermore, under groundwater seepage, the shape and size of the tunnel cross section have significant effects on the interface temperature. Fourth, the cold region tunnel has an antifreezing capability that is mainly related to the frost heaving of the surrounding rock and the groundwater seepage velocity. This capability should be fully utilized in the design of cold region tunnels. The experimental data presented can be used to verify the reliability of the theoretical calculation model for tunnel temperatures in cold regions.
