What specifications are used for monitoring and measurement of tunnels?

1. The following specifications are used for tunnel monitoring and measurement:

1) TB10121-2007 Technical Specification for Monitoring and Measurement of Railway Tunnels;

2)JGJ8-2007 Code for Building Deformation Measurement;

3)JTG F60-2009 Technical Specification for Highway Tunnel Construction.

2, through monitoring and measurement to achieve the following purposes:

1) Monitor the stress and deformation of surrounding rock to ensure the stability of supporting structure and the safety of surface buildings and underground pipelines.

2) Provide a basis for judging the basic stability of surrounding rock and initial support.

3) Understand the scientificity and rationality of construction methods and means through monitoring and measurement, so as to adjust construction methods in time and ensure construction safety.

4) Through the analysis of the measured data, we can master the changing law of surrounding rock stability, provide the basis for modifying or determining the design parameters of the supporting structure, and determine the arrangement of subsequent processes.
