近些年来地质矿产部水文地质工程地质技术方法研究所在岩土声波检测技术方面取得较大进展。研制了数字化岩体声波检测仪,“纯”横波换能器,及全波列声波测井仪等岩、土混凝土声波横波检测技术方法,以及宽频带窄脉冲超声换能器的研制。同时开展了桩基无损检测、地基常时微动观测、声波跨孔法大距离深、干孔岩体裂缝探测。
In recent years, the Research Institute of Geology and Mineral Resources of the Ministry of Geology and Mineral Resources has made great progress in rock and soil acoustic wave detection technology. Developed digital rock mass acoustic wave detectors, “pure” shear wave transducers, and full wave column acoustic logging tools and other rock and soil concrete acoustic wave shear wave detection techniques, as well as the development of broadband narrow pulse ultrasonic transducers. At the same time, the non-destructive testing of pile foundations, frequent micro-motion observations of foundations, large distances of sound waves across holes, and exploration of rock fractures in dry holes have been carried out.
