Stress calculation of unlined pressure tunnel surrounding rock in hydraulic engineering
2013 2nd International Symposium on Instrumentation and Measurement, Sensor Network and Automation (IMSNA), 2013In hydraulic engineering, the running state of pressure diversion tunnel directly affects the normal use and economic benefit of the whole project. This paper bases on the deep-lying circular tunnel and analyse stress distribution in the unlined hydraulic tunnel surrounding rock by using the finite element method, respectively study the stress after ...

Deformation and failure study of surrounding rocks of dynamic pressure roadways in deep mines
Mining Science and Technology (China), 2010Abstract In order to understand the change rules of stress-displacement in surrounding rocks of dynamic pressure roadways in deep mines and to obtain a theoretical basis for analyses of roadway stability and designs of support, we established a coupling equation of adjacent rock strength, mining stress and supporting resistance on the basis of an ...

In order to identify the pressure arch of the surrounding rock in shallow-buried rock tunnels and quantitatively evaluate its global stability, a boundary identification index α and a global safety factor S of the pressure arch were proposed. When α is the change rate of the ratio of radial and tangential stresses, and the value of α at the extreme ...
