摘要

本文简要地评估了土力学现场测量中常用的连杆式应变传感器的力学匹配误差。对一种特殊的

匹配误差小的非接触互感式传感器的特性作出分析。设计了与这种传感器配用的

适合于动、静态测量的土壤应变仪

给出了它的主要性能指标。

Abstract

A brief review of the errors from mechanical mismatch of ‘Spool Gage’ commonly used in field soil strain measurement is made. The behavior of a unique contactless magnetic coil gage is analyzed

which is relatively free from mechanical mismatch effects. The structure and main specifications of the instrument designed for the measurements of both static and dynamic strain in soil are presented here.
