Application of Elastic Wave CT Technique on Detection of Fracture Zone in the Rock Mass of Dazu Stone Carvings

摘要: 大足石刻是中国现存的重要石质文物之一，具有重要的历史和文化价值，其中有的石刻造像曾被列为国家石质文物保护“一号工程”；最近，文物保护部门又启动了对危岩体的加固和防渗工程。为确定大足石刻宝顶山大佛湾岩体中破碎带发育情况，应用跨孔弹性波CT技术对指定位置的工程岩体进行了探测。CT探测得到的岩体弹性波速成像清楚地揭示了两个钻孔之间岩体中破碎带的规模和产状，与岩体所在的区域地质构造应力场作用协调一致，证明了探测成像结果的可靠性，为大佛湾岩体的渗流和稳定性评估提供了依据。Abstract: Dazu Stone Carvings is one of important stone relics existent in China, which has significant historical and cultural values to this world, one of which had been once listed as "first protect engineering" of stone relics in China. Recently, a new round protecting engineering, including reinforcement of dangerous rock masses and seepage treatment of rock masses, is started by department of cultural relics protection. In order to determine situation of fracture zones developed in the rock masses of Dafowan in Mount Baodingshan, one spot of Dazu Stone Carvings, a detecting work based on cross-hole elastic wave CT technique is carried out on the position designated. The velocity imaging of rock mass between holes resulted from the detecting work clearly reveals the scales and space attitudes of fracture zones in the rock mass between holes. The reliability of the imaging result is demonstrated by the compatibility of the fracture zones with the tectonic stress field of regional geological structures, and the detecting result provides a reliable reference for the analysis of seepage and stability of Dafowan rock masses.
