| Abstract: | A test of continuously observing strain changes in soil has been recording data for over three years in Wenan, Hebei province. A YRY 4 type borehole strainmeter of high resolution is used for the horizontal strain observation. The self checking function of the YRY 4 strainmeter which has four gages ensuring the reliability of the data. Relative in situ calibration is applied to evaluate the operation of the instrument, as well as correct the readings, which is very significant for precisely calculating the principal orientation of changes. Thus data credibility of four gages borehole strainmeter is defined here. A correction using the result of relative in situ calibration entails high data credibility of the YRY 4 strainmeter at Wenan, indicates that it has been working well. |
