Abstract Due to the external dynamic geological process, the protection of Dazu Rock Carvings sites needs high precision geological engineering survey data, and the digital borehole panoramic camera technique can accurately obtain the structure characteristics and underground rock mass discontinuities with precision of 1 mm. In this study, the authors used digital panoramic borehole camera technique to analyze the geotechnical engineering of Thousand-Hand Kwan-yin at Dazu, Chongqing, and the results show that the integrity of the rock mass in this region is good, with the discontinuities being mainly manifested as joints and constituting the main seepage channel in the region. This technique can provide original imaging data for the geotechnical engineering of Thousand-Hand Kwan-yin. It offers a advantage for the protection of cultural relics sites, which improves the implementation and decision-making of engineering.
