摘要
压电陶瓷弯曲元是一种多功能传感器,在国外已经被应用于测试土的剪切波速和研究土的工程性质。该文介绍了在HX-100型动三轴仪上开发的压电陶瓷弯曲元剪切波速的测试装置,并对多种不同物理性质的试样,用弯曲元测试装置进行试验,试验结果与共振柱仪室内试验的结果非常吻合。同时,利用此试验装置,参与了国际平行试验,并获得好评。
Piezoceramic bender elements are versatile transducers and are widely installed in soil instruments to measure shear velocity and small- strain shear modulus of soil. A developed HX- 100 static/dynamic tfiaxial apparatus with the installation of bender elements to measure shear wave velocity of soil is introduced. Laboratory tests were car- fled out on several kinds of soils, and the tests results show that results obtained by bender elements coincide with those collected by Drnevich Long- Tor apparatus very well. With this apparatus, we took part in international parallel tests organized by TC- 29 aimed at improving element bender testing technique and obtained good reputation.
