Application Of Geo-detective Radar To Inspection Of Tunnel Lining Quality

Nowadays, with the pressing value of railway tunnel construction quality, The schedule of inspection of building tunnel is now been paid to the which will be necessary. Technique of non-destructive detection, characterized by non-destruction, rapidness, convenience and economy, is employed extensively. As for non-destructive inspection of t railway tunnel lining quality, the two principal indices are strength and depth of lining, of which the latter will only be investigated in this paper.It demonstrates the knowledge and application of geo-detective Radar, as well as mainly elaborates on the principles of inspection of tunnel lining depth (including depth of concrete as lining; internal defects and the degree of compaction lining backward etc.); combining the case practice in the inspection of depth and defects of many tunnels, it demonstrates the outstanding effect of geo-detective Radar when it is applied to the inspection of tunnel lining depth.
