摘要

由于外动力地质作用,大足石刻造像遗址的保护工程急需高精度的地质工程勘察数据,而数字全景钻孔摄像技术能够精确地获得地下岩体的结构特征与精度1 mm的结构面信息。利用数字全景钻孔摄像技术对重庆大足千手观音附近的岩土地质工程进行勘察分析,结果表明:区域内岩体的完整性整体较好,结构面主要表现为节理,并构成了区内的主要渗水通道。数字全景钻孔摄像技术为大足千手观音的岩土工程勘察提供了原始图像数据,方便了大足千手观音文物遗址保护工程的实施与决策。

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.

Key words： digital panoramic borehole camera rock mass discontinuity Dazu Rock Carvings engineering for cultural relic protection
