Monitoring and Analysis of Surrounding Rock Deformation of Wubang Tunnel of Xia-Rong Highway

The geological condition of Wubang tunnel in Guizhou is introduced in this paper.The article established the scheme,which determined the method,items and contents of in-situ measurement.The stable standard of surrounding rock was proposed as well.On the basis of these,the construction process was monitored.Then the data of the surrounding rock deformation was analyzed,including arck settlement,section convergence and surface subsidence.The reason and development principle were discussed in the end.The achieved results could take good effect in guiding construction.
