Application of comprehensive inspection technology in defect inspection of expressway tunnels
In the defect inspection of highway tunnel,it is impossible to analyze the validity,authenticity and reliability through a single detection method,which will cause some misdirection to the design in the later stage.This paper focuses on the comprehensive application of geological radar scanning,multi-channel observation instrument,steel bar scanner,drilling core and other detection technologies in the inspection of highway tunnel defects,and collects comprehensive effectiveness data for comprehensive analysis and judgment,so as to guide the later defect control design work.
