摘要
本文介绍了YT型压电式岩体动应力传感器结构、工作原理、主要设计思想和压电量测系统,简述了其主要性能的试验方法和试验结果,并对现场应用情况作了介绍。大量性能试验和实际应用表明,该传感器用于爆炸冲击条件下,在岩体、混凝土等介质中测量具有变化快、量程宽特点的动应力,是较为理想的。
In this paper, the construction, working principle, main design idea and measuring system of piezoelectric transducer (Model YT) for measuring dynamic pressure in rock are introduced. The procedures and results of main characteristic tests as well as the practical application in situ are briefly described. It is shown that the transducer is satisfactory to measure the dynomic pressure ia rock and concrete with good frequency response aad wide measure range in blast circumstances.
