摘要
介绍超声波探测在石质文物风化评价、化学加固效果评价及其裂隙研究方面的应用，并将其结果与目前常用的方法进行了比较。
The ultrasonic velocity in stone depends on the water saturation and especially on the density, the general condition of the stone. Therefore the ultrasonic velocity is a suitable tool for the assessment of stone.Ultrasonic investigations could provide more informations about: general condition of the weathering phenomena. depth of the weathering zonel extension of the fissures, as well as for quality assessment in the consolidation and restoration of stoneworks.This paper reports the application of ultrasonic mesurements in the conservation of sand stone at Dafusi grotto in Shanxi province. Confirmed by the other methods used in conservation of stone, the results showed that ultrasonic investigation is very helpful for the interpretation of stone conservation and restoration.
