The Automatic and Real Time Measurement of Tunnel Surrounding Rock Deformation
Applied Mechanics and Materials, 2013We 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 ...

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.

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 ...
