Abstract: In order to guarantee the safety and quality of the construction, geological radar is used to detect the geological conditions and the construction quality. The accuracy of the geological radar detection can be improved by means of interpretation on the interfering images. In the paper, analysis in made on the images of the geological radar detection induced by the highvoltage power line, lining formwork trolley and niches. The paper can provide reference for the image interpretation in geological radar detection in the future. 

Key words: geological radar, image interpretation, interfering factor
