碩士 === 國立中興大學 === 土木工程學系所 === 105 === In this thesis, the calibration of inclinometers was performed by using the self-developed frame based on the geometric principles. The calibration frame is capable of measuring a tiny change in vertical angle with an accuracy of 0.000143 degree. Firstly, the study carried out the calibration of inclinometers with the calibration frame in the laboratory. The calibration factor of each inclinometer was obtained through the calibration process. Secondly, field measurement on a 20-m deep inclinometer casing was performed to investigate the feasibility of using the calibration factor to correct the measurement readings. The results obtained from the study show that very consistent results were found for two different inclinometers after the measurement readings were corrected by multiplying the calibration factor.
