Abstract: | Starting with tunnel lining detection,this paper discusses poor accuracy in the detection of lining thickness caused by negligence or disappreciation of dielectric constant correcting,mileage marking or antenna control,in respect of which analysis is carried out successively and their large effect on the accuracy of detection is proved.As a result,it is stressed that the keys in these links should be grasped carefully in practice,ensuring the accuracy in such detection. |
