Upper Bound Solution of Surrounding Rock Pressure for Deep Cavity Using Nonlinear Hoek–Brown Failure Criterion
The linear failure criterion is generally adopted in the stability problem of geotechnical engineering, whereas the experiments have indicated that there is a nonlinear relationship between the maximum and minimum principal stresses in weak surrounding rock. According to the characteristics of weak…

Study on deterioration, cracking mechanism and treatment measures of plain concrete lining with cold joints in high-speed railroad tunnel
Cracks in lining will lead to derivative diseases even seriously threaten the safety of high-speed trains. Construction-induced defects and external environmental changes are the main causes of lining cracks. From a typical high-speed railroad tunnel with a large number of lining cracks in China…
