Scope
This standard specifies the technical requirements for monitoring of soft rock tunnels, monitoring measurement methods, data analysis, and information feedback. This specification is applicable to tunnels in newly built, reconstructed, and expanded railways, highways, and urban roads, with an actual rock mass grade of Class IV or lower and actual monitoring deformation exceeding 1.5 times the deformation allowance originally designed in the tunnel.
