Theoretical analysis of additional surrounding rock pressure in shallow buried bias tunnel. [PDF]
Sci RepThe existing calculation method for the surrounding rock pressure of shallow buried bias tunnel fails to account for the impact of the progressive failure characteristics of the surrounding rock and slope creep, thereby neglecting the additional pressure arising from slope creep.

Advances in Civil Engineering, 2022 The influence mechanisms of factors, such as high confining pressure and in situ stress caused by deep mining on the stability of surrounding rock of roadways, are complex. Particularly, the motion and energy release of the rock mass medium can be caused by vibration transmission induced by blasting excavation in the underground mining.

Hydraulic Transient Impact on Surrounding Rock Mass of Unlined Pressure Tunnels
Water, 2023 The frequent pressure pulsations due to hydraulic transients in hydropower plants induce cyclic loading on the rock mass that may contribute to increased instances of block falls and increased risk of tunnel collapse over the power plant lifetime. This study focuses on understanding the effect of frequent start and stop sequences of hydropower in ...

Analysis of Surrounding Rock Pressure of Deep Buried Tunnel considering the Influence of Seepage
Geofluids, 2022 This paper takes the surrounding rock of deep tunnel as the research object and considers the action mechanism under the influence of seepage. Based on the Mohr-Coulomb criterion, the stress mechanism of surrounding rock of deep buried tunnel is analyzed by a convergence constraint method.

General Formulas for Calculating Surrounding Rock Pressure of Tunnels and Underground Spaces
KSCE Journal of Civil Engineering, 2020 Through the analysis of the statistical data from a large number of existing tunnels and underground space engineering projects, the limitations of the commonly used formulas for calculating the surrounding rock pressure of tunnels are examined, and the calculated values were compared with the measured values to reveal the differences between them.
