(5) The detection efficiency is low; 6) high cost and the like.
The defects can be obtained, and the current situation of the advanced detection technology applied to the existing tunneling surface is that the method is more, the working procedures are more, the result is more, and the cost is more; and the detection is less, the integrated operation is less, the optimized operation is less, and the accurate forecast is less.
