Torsion test of slope inclinometer tube and measured value correction

In order to quantitatively understand the torsion condition and inspection method of inclinometer tube in practical projects, as well as the correction method of deformation measurement value based on torsion measurement results, the application process of professional torsion meter is given, and the causes of torsion of inclinometer tube and the correction process of measurement value according to the measured torsion angle are analyzed. Taking the CF01 and CF02 inclinometer tubes installed on the intake slope of a hydropower station project as an example, the geometric correction and coordinate transformation methods are used to study the torsion of the inclinometer tube guide groove and the correction process of the measured value, and the influence of the existing torsion degree on the measured value is analyzed. The specific project proves that the research method is reasonable and reliable, and the selected torsion meter is reliable, which has a certain reference value for similar projects.
