In this paper, a prototype load test on cracked shield tunnel lining segment was conducted to study fracture properties of the segment with initial crack. Principle and process of the test were introduced, and test phenomena were detailedly depicted. Experimental results reveal that lining segment with initial crack finally shows the I-type fracture property, and the failure mode is dominated b…
Taking Jiangluling tunnel as an example, a numerical model for investigating the evolution of the frost penetration and ablation in the surrounding rock of cold region tunnels is presented based on the governing equations of the coupling problem of temperature and air flow fields in cold region tunnels. As the tunnel starts to operate and cold air flows in, frost penetration starts. The thawe…
Taking jiangluling tunnel as an example, a numerical model for investigating the evolution of the frost penetration and ablation in the surrounding rock of cold region tunnels is presented based on the governing equations of the coupling problem of temperature and air flows in, cold region tunnels. As the tunnel starts to operate and cold air flows in, frost penetration stars. The thawed permaf…
To reveal the reason for moisture condensation of an I-shaped pedestrian underpass in the summer, which is widely constructed in many large southern cities of China, its ventilation effect was investigated under a hot, rainy, and humid climate condition. Through in situ monitoring of the Yuejiazui I-shaped pedestrian underpass in Wuhan City, China, some internal environment parameters, such a…
