二年前,英国《水力发电与坝工建设》杂志上介绍了一篇有关应用振音技术监视土坝稳定的报告(见“水力发电与坝工建设”1976年第4期,我所已作翻译,并进行了资料交流——译者)。作者现在认为,这项技术已可以付诸实践,并准备进行现场试验。振音意指土体颗粒移动时,土体所发出的声响。鉴于土体颗粒的这种位移通常是由应力 Two years ago, the British magazine Hydropower and Dam Construction introduced a report on monitoring the stability of earth dams using vibro-acoustic technology (see “Hydroelectric Power and Dam Construction”, Issue 4, 1976, Translation, and the exchange of information - translator). The author now believes that this technology can be put into practice and ready for field trials. Vibrato means the sound of the soil when the soil particles move. In view of this displacement of soil particles is usually caused by stress
