Xian710043) Abstract: The safety of tunnel supporting structure is influenced by swelling ratio, swelling force and distribution range
Under the background of Xining tunnel construction of Lanzhou-Xinjiang second track, an estimate and suggestion of tunnel lining safety are done based on the water physical properties analysis and the engineering characteristics of swelling rock
It can serve as a reference for similar engineering construction
