乾陵石刻内部裂隙的超声波探测研究

利用岩石与超声波波速之间的相关关系，对乾陵不同截面形状的石刻分别进行了网格法、层析法的超声波现场布点探测，通过测定、计算，估测出所测石刻断面内部各点(或区域)的超声波波速分布及变化规律，并辅以反射波法来进一步确定石刻内部结构情况，从而探测出石刻内部的裂隙或风化情况。

Studies on internal fissures and fractures of stone sculptures by ultrasonic techniques

Based on the relations between natural stones and ultrasonic velocity, an ultrasonic netting and tomographic procedure have been applied for the in - situ study of the internal state of deterioration of different cross - section shaped stone sculptures in Qianling Mausoleum. With the data measure and calculated, a distribution diagram of ultrasonic velocity across the whole cross - section could be got, and helped by the reflective ultrasonic method, an evaluation of fissures and fractures extended internal thus could be detected correspondingly.
