JQ-1型钻孔式剪切应变仪总体设计
|
摘要
<正>一、前言在组合应变仪的设计中,曾提出了更为直接测量水平剪切应变的新的工作原理。本文首次报道了采用这一新测量原理、配合以新式的机械结构和新型电路构成的JQ-1型钻孔式剪切应变仪。 1．新的测量原理即没有采用传统的径向位移式测量方法,而是采用弹性筒内壁的切向位移测量方法。它的优点：一是井下仪器(探头)内部只用两个传感元件直接给出两个测量量(而不是传
This is the first time to report the total design of JQ-1 type drill-hole shear-strain-meter. New observatory principle, new structure and new circuitry have been adopted; we attempted to make it has better capability and performance. As the second generation of a kind of continuum strain variation observatory technique, after the FYZ-1 type multi-component strain-meter. JQ-1 type strain-meter can be mounted in the integrated observatory instruments in shallow or deep drill-holes, or, independently works alone. It may carry through 2-dimensiona1, or, 4-dimensional observations, and strictly able to do self-checking observation data. We believe that JQ-1 type strain-meter would have a bright foreground usage in seismic monitor and prediction experiment of this country.
