超动态应变仪的研制和现场应用

Ultra-dynamic Stfain Gauge and Its Field Applications

介绍了ＹＣＤ－１型超动态应变仪的研制、设计原理和主要特点，及在爆破近区应变测试中的应用。该机已投入隔河岩、前坪三峡模型试验场和葛洲坝二江自备电厂等工程爆破现场应用，文章对应用结果作了初步评价。

This paper describes the development,design principle and main features of type YCD-1 ul-tra-dynamic strain gauge ,and the application of it to strain testing in the near-blasting field.Thisgauge has been used in many engineering blasting fields,such as the Geheyan project ,experimentalbase of the Three Gorges project and Gezhouba selfpowered station. In this paper,preliminary evalua-tion is made to applied result.
