Forecast Study on Large Deformation of Surrounding Rocks in Mountain Tunnels

Applied Mechanics and Materials, 2012
Shilin tunnel is a separated bi-directional four-lane highway tunnel, and its distinctive geological conditions and fault structure result in frequent geological disaster like large deformation. Construction of tunnels were seriously hampered, and the project was delayed, and the cost increases simultaneously.

The Automatic and Real Time Measurement of Tunnel Surrounding Rock Deformation

Applied Mechanics and Materials, 2013
We designed a tunnel surrounding rock(TSR) deformation automatic and real time measurement system .The long distance laser datum line instrument (LDLI) is fixed in stable ceiling rock of the tunnel. The LDLI transmits a bunch of lateral linear benchmark beam with small facula, and projects to the linear array CCD which mounted on instable surrounding ...

Application of GRNN in Time Series Prediction for Deformation of Surrounding Rocks in Soft Rock Roadway

2011 Fourth International Conference on Intelligent Computation Technology and Automation, 2011
During soft rock roadway construction, the deformation of surrounding rocks is a significant factor in stability evaluation. However, the deformation still has long duration, obvious nonlinear effect after the soft rock roadway construction accomplishment. Certainly, this potential stability change will make the maintenance cost increased in the future.

Mechanical Properties and Deformation and Failure Characteristics of Surrounding Rocks of Tunnels Excavated in Soft Rocks

Geotechnical and Geological Engineering, 2017
As soft rocks are likely to soften, slime and swell while contacting water, the existence of soft rocks is harmful for stability of surrounding rocks and supporting structures of tunnels. Through uniaxial and triaxial tests under dry condition and triaxial test with different moisture contents, the mechanical properties and failure modes of soft rocks ...
