MONITORING IMPLEMENTATION AND DATA ANALYSIS ABOUT A CROSS-SECTION OF THE TUNNEL CONSTRUCTION

The article combined the rock surrounding displacement and vaults sink monitoring and measurement of the KeShan Tunnel construction,including the method of measurement and the arrange of the measuring points and so on,analysis of the collation data of the scene monitoring and measuring.Directly based on the results of the measurement criterion to determine the stability of surrounding rock and support system working state,and more accurately grasp the time of surrounding rock stabilized,we provide a reliable basis for construction safety and determine a reasonable construction for secondary lining,and also provide a reference for the future other similar tunnel project monitoring and measuring the implementation and experience.
