Abstract: NDT is called non-destructive testing and it does not affect the performance of the materials.The detecting objects is using ray, ultrasound, infrared, electromagnetic technology, the instrument of material and equipment in defect detection technology. In order to understand the current status of non-destructive detection of development and improve the quality of non-destructive testing,it contrast introduce five ways to analyze their strengths and weaknesses. The results showed that: traditional detection methods have been unable to meet the current needs of the project development. its accuracy, security can not better serve the project. Geological radar method is safe, convenient, fast outcome advantages.It plays an important role in the tunnel non-destructive testing. The future development of geological radar technology will be more precise, easy and convenient.
